look up any word, like pussy:
 
1.
literally: a large, lumpy, generally amorphus baked good.

in "urban" speak: descriptive of the view of a girl from behind. Not just the ass, but the entire view.

a girl with a "backside like baked brown betty" is only has to be a little bit chubby. The backside is riddled with any of the following flaws:

back boobs
puffy shoulders
muffin top
complete lack of ass- (waist wider than hips)
Oh snap, shawty's got a backside like baked brown betty. that's just a shame.
