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."

When popped, it resembles a river of cum flowing to Brown town.

A beggar, like the ones in big cities that ask for change, but instead of change, he wants cum shots. Therefore, he is the "Cum Bum."
Man: "I was walking down Jefferson in Chicago, and I saw this guy coming up to me. I thought he was gonna ask me for some change, but he wanted my semen. Isn't that gross??"
Other Man: "Yeah dude, that's fucking sick. He's the Cum Bum!!"
