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!!"
