One who likes to perform anal intercourse.

Plural: BunBusters

Also the name of a short-lived series of Porn Movies by "The Dark Brothers".

My girl Pam sure likes it up the ass. Just call me 'The Bunbuster'.

Lyricslyrics from the porn movie follow:

"Baby, I was just sittin' here, lookin' at the stars, and thinkin' about that time we tried anal sex...
And it didn't work out...
Well, Baby, I want you to listen good, 'cause ya know what I'm gonna do? I'm gonna call the White Bun Busters...
And they're gonna bust yer fuckin' buns!!!"
