If you move at least 30 feet in a straight line immediately before making a melee attack with an unarmed strike or similar (I.E. Ramming a creature as a satyr) you gain one bonus damage die for every 30 feet you move before the attack to a maximum of 5 extra die. Alternatively you can attempt to shove a creature and pushing them 10 feet per 30 feet of movement on a success to a maximum of 50 feet.
