"Oh Look at her...thats a real mum bum..." or "Look at her she aint got no junk in that trunk, she got mum bum"....
well look at the bums of some moms and you'll see what we mean.... it's very obvious!!(looks like you've spent the last 3 days laying on your back and your ass is flattened...)

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.

phantom bumming is when you take a picture of a friend stood right behind someone else who is bending over although the person who is bending over shouldn't be aware of this occuring when you look at he picture it should look like your friend is making love to their bottoms.
i got an imense phantom bum at the co-op.
i dare you to phantom bum that old lady.
i hope i didn't just get phantom bummed when i picked that up.
i bet i can phantom bum your mum.
