our party was hunting pirates as a side quest in tomb of annihilation and my friend tried to introduce his new character as a pirate trying to cause a mutiny right when we showed up then he would join us and beat up the pirates with us. Instead, we stayed in character and when he came near us, we shot at him and now being an enemy to the pirates both sides shot at him till he died. His character only lived for a record time of 15 minutes

 I feel sorry for that poor pirate. LOL.

 Sounds like a d*ck move on your party's side, chief

my party explored a Gnome fortress, UNSUPERVISED. They Knew that these Gnomes were driven by a Paranoid and Insane ruler. long story short, Rogue almost falls three hundred feet into the mouth of a Mimic while the Bard becomes a Demon.

I was trying to fight a goblin and kept rolling nat 1s, so my character the entire time was cursing… good times

My friend decided he really wanted to steal the gold from behind the sleeping giant. Well long story short the giant killed and cooked him to feed to the massive vulture. We don’t ever get close to giants anymore. 

Long story short, my party was battling a sea monster, it had already eaten two of them, so my fighter decided to swing from one of its tentacles and jump inside of its mouth and then attempt to great axe through its throat. The sea monster fared worse...

One time, a party I was DMing tried to take on the Adult Green Dragon that was antagonizing them the whole campaign. At level 3. There were only 3 people on the team, and none of them were spellcasters. I used my one DM mercy and let the party excape while the dragon got food poisoning from the cattle it ate and kept throwing up.

The level 2 party is trying to calm down a wyrmling that escaped from a circus. The bard is playing the Minecraft theme, and are about to calm it down, when the paladin casts Thunderous Smite. That did not go well. Both the bard and the Druid almost died.

"We need to befriend this monster! Hey - WHY'ED YOU JUST ATTACK IT WITH THUNDER!"

 My friend, after the bard starts playing the Minecraft theme; “Did you pull a piano out of your ass?”

We're in a dungeon and...

Me: "I am going to expend a charge from my Wand of Detect Magic to cast detect magic."

DM: "You see a large aura of evocation magic coming from this set of double doors." (Points to map.)

Me: "Guy's, we need to be careful, I think that door is trapped."

Rogue: "I run towards the door and open it."

Long story short, the rogue loses 1/3 of his hit point maximum as the door launches a bunch of fire and stuff. Then, we have to fight the big boss battle unprepared which results in my character getting thrown out the fourth story window by his own ally.

my players, after defeating a group of Giant Rats, decided that - to avoid further combat with the creatures - they'll disguise themselves. they skin the corpses of the Giant Rats in the room and wear their pelts like big, smelly clothes. I allowed them, knowing full well there were no further Giant Rats in the adventure

that was rather genius on their part, though. the real stupid part is I forgot they'd done that, and when they interacted with the NPC again, he made no comment on the bloodied Giant Rat hides that the party was wearing. I gotta get better at DMing and notetaking at the same time lmao

During one the one-shots - we had this situation, fight scene in the city where war between two factions take on scale.

We have to block the fanatics in alley. We picked up higher ground and fortify top of the stairs leading to major home. Stairs were steep (10ft up on 15ft uproach) 

and then after like 15 min of long heroic fight our barbarian/paladin (yes) decided to break enemy morale by killing guy with drum and banner so he CHARGE and said to DM that he will JUMP on him try to knock him down prone with super-heroic jump with his glave high to cleave his path.

okay so he jump. 10ft up from 10fh steep stairs (20ft higher comparing to ppl on the ground below) and fail his athletic skill check

we all: guidance . bard inspiration and best of it barbarian/paladin LUCKY feat did not save him from neck breaking NATURAL ONE XD

Ok me and my party were all 3rd lv and were fighting some awakened trees in the middle of a forest when the Aarakocra Artificer (Artilerist) flew up and dove back down wielding his flamethrower cannon, burning the remaining trees to death but also causing the rest of the party and the forest to go up in flames. That's when the Druid wild shaped into a bear and turned on the Artificer lol.

*long sigh* so I was DMing some Theros with my friends Uncle B, Biscuit, and my sister Jimmy (all of these names are fake ofc). Biscuit was playing as a Nyxborn created by Heliod or something, Jimmy was an oracle, and Uncle B was playing as a druid. So, the session starts at Meletis during Heliod's festival, and Biscuit, decides to steal a priest's underwear. Why he did this? I know not... So after he succeeds very well, Jimmy also decides to get in on the underwear stealing action and some guards get involved! So, as they're cornered Biscuit decides to *sigh* steal a guard's underwear.... So I ask him to roll and then I say "You feel around for underwear... but you feel none" Everyone at the table goes absolutely insane. The guard is absolutely horrified and Jimmy and Biscuit are promptly arrested... I reaaalllyy dont know what happened there... 

After that incident I decided to send them off on an Oddesey of sorts to get them as far away from civilization as possible

So the party's in a massive fight with a bunch of baddies all over the place. The bard and several other party members are trying to fight a wizard/alchemist whose throwing dangerous vials out the window and dealing a bunch of damage every turn. They were fortified in the building so it was really hard to get to them. There was also some sort of mechanical dog with the mage that we can hear barking.

Anyway, the party is unable to get inside the building they're in, so we all go to another part of the fight to attack some ogres and stuff. Our thought process was that the mage couldn't escape because they'd have to get out of the first floor of the building and even while taking on the other thing, we had a line of sight to see if it tried to escape. Once we handled the other stuff, we could come back to it all together and avoid taking damage in the first place in the meantime.

But the bard thought differently: While we all fled, they stayed behind and decided to smash the window of the house, take some damage, and run in.

Remember the clockwork dog I mentioned earlier? Well the bard was already at fairly low HP, and one hit from the dog completely knocked them unconscious.

The dog just sat there as the bard bled out to death. Sad end for that poor bard, they were very wise and totally great at decision making:)

Did not happen to me, but I have heard rumors of a party that found the Eye of Vecna, then the Hand of Vecna, both in a large dungeon.  Then they were presented with a head, missing an eye, in a glass case labelled "Head of Vecna".

Yes, one of them was stupid enough to cut off his own head after his getting a promise from his servant to put the "Head of Vecna" on his body.

1. A wooden tavern had a metal door. There was VITAL information inside we needed. My party member saw the door was locked, hit the METAL DOOR ON A WOODEN BUILDING WITH LIGHTNING, and burned down the tavern and almost killed 2 members of the party

2. We were in a VERY small and enclosed room with a npc that a party member decided to kill. he them proceeded to USE THUNDERCLAP in the tiny room that we soon found out was METAL, and we all almost died at like literally level 3 (it was a different person than the first lol)

1. RAW, lightning doesn't set things on fire and doesn't have any particular effect on metallic objects. However, a DM could rule it as the attack being done with advantage.
2. Thunderclap deals thunder damage, i.e a sound so loud that it causes a shockwave that hurts you. It has nothing to do with electricity. The presence of metal is irrelevant, both within the RAW and the laws of physics.

I was attacking an ice troll at the bottom of a crashed ship, siping it from the deck. I did a beautiful nat 20 and just exploded him with chromatic orb, But it triggered a wild magic surge, and exploded the entire ship and the party with fireball!

I doubt one fireball is enough to blow up an entire ship. Depending on its size, the hull of a ship has 100 to 500 hit points.

The second time I ever played I was pushed out of a cart and knocked out for half of the game. I was a Gnome and the DM decided she didn't like my character very much. Another player pushed me out of the cart, fair play on her behalf, and I kept rolling super poorly so stayed unconscious for quite a long time. One of the other players carried me around on their back but wouldn't help to heal me as they found the whole ordeal humorous. 

This sounds more like a horror story than the premise of this thread. The people you played with basically bullied you out of game by removing you from play and forcing you to be a spectator.

a lvl 4 barbarian (beserker) gnome (the rock or something like that one) verbally assaulted a really popular alchemist/pharmacist (half-elf or something like that)in the only town anywhere near where we were. Lets just say we are not only hated by the town members, but we are also banned from more or less every store in town because of him.

The other PCs should have publicly disavowed the barbarian, either by turning him over to the local authorities or by kicking him out of the group whenever they're in town.

Me and my party were traveling by boat and we were being stopped by a bunch of mermaids. Earlier in the campaign we slayed a drider and the mermaids had a problem with the same drider. So they asked for its head, and if we gave them their head they would let us pass. Our bard said that we had it's head and casted minor illusion to make a head appear on his hand. It didn't go well, let's just say we had to swim to shore afterward.

There was that one time we were all level 1, and we had an arsonist on our team. Long story short, we burned down an orphanage and made all of the kids live in a barber shop that we had vandalized 15 minutes beforehand, all because of a talking cow called Moo-Doo-Bodonkoo-Mc-Moo. Any time we pronounced the cow's name wrong, we were kicked away 30 feet.

Basically we were in an inn, and a bunch of gnolls kicked down the door and started terrorising the people, so we got to work. Fireball and Lightning Bolt were both cast, and several gnolls were smashed through windows and hung up on wooden chandeliers, all resulting in a lot of property damage.
