Fat Grenade 

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!

fat pooper 

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".

Oh my, look at Lindsey! Her jeans look painted on. She's got one fat pooper!
