A woman's nice yummy buttocks. Usually young and plump in nature. They come in all kinds of shapes and sizes. When in the field of vision of a Yum Bum it drives you wild. Almost to the point of biting your lips.
Whippersnapper: Hey Sammy, look at those delicious Yum Bums. Looks so nice I almost bit my lip.
Whipper's friend: Yes I agree, those Yum Bums are the tops.
