Short acronym for:
Eat A Dick.
Originated from the mmorpg
game WoW, By the guild Intensity. After winning a massive battle, the leader of the guild spamed in the game EAD
Mother Fuckers.
Mispelling the word 'Dead'. Hence how the word 'ead' orginated.
After sometime, EAD is now known as a short acronym for
Eat A Dick.
