Nasty cum or sperm that is ejaculated from a bum, a bum that is nasty and lives in the woods usually. the cum may be brown or yellow, if your unlucky it may be bloody and white. bum cum is not something to mess with, its so sticky and powerful it could stick you to a tree if a bum attacks with his cum.
"guess what happened to john out in the graveyard woods?"
"what?"
"some bums attacked him and ejected their bum-cum all over him."

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."
