Fk yeah's definitions
The posterior side of an attractive female. An ass of extraordinary quality. Big, round and most times heart shaped. Often found on nice gals. Not to be mistaken for a "fat ass".

Get the fat pooper mug.A female who is on the verge of "blowing up". A lil chubby but not fat...yet. Has great potential to look like her mother.
That beech is kinda hot but she's a total fat grenade. She looks like she's one burger away from exploding!
