Bum Gum

When one's body doesn't digest gum and they poop it out.

Man, what are you chewing on, it smells like bum gum.
Swallowing all of that Bazooka allowed me to produce my very own bum gum!
When that girl gave me a hot rodney, she proceeded to chew on my bum gum. sick ass.

A woman's labia. Self-explanatory.

All I wanna do,
Is chew, chew, chew,
On her bubble-gum-by-the-bum
