Crunchy's Obnoxious Flatulence

When you target a creature with this spell, that creature must make a Constitution saving throw versus the spell caster's spell save dc. On a failure the creature begins to fart loudly and uncontrollably. The combination of the smell and noise makes it difficult to hide or take seriously in a social environment. The creature has disadvantage on stealth checks and all social skill checks (such as persuasion,  intimidation, or deception). This effect lasts until the caster loses concentration or the spell ends.
