"Candy" of abysmally poor quality which The Poopsmith gives to oblivious trick or treaters such as Homestar Runner on Halloween. Definitely not equal to a million pounds of candy, especially if you're going for quality over quantity like Bubs is.

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."
