Cum Bum 

The act of taking a jizz on a woman's ass while she's still wearing her pants. The result of the man's unwillingness to wait for sex with his old lady creates a white stain on the woman's pants that is extremely difficult to get rid of.

Jerk #1 - "Yo brotha, there's a white stain on the back of your girlfriend's pants."

Jerk #2 - "I know. Last night I was so anxious to have sex with her, but I ended up giving her a cum bum instead."

Jerk #1 - "Word."
