An insult similar to cocksucker. Originates from the song "Uncle Fucka," performed by comedians Terrence and Phillip" in the movie "South Park: Bigger, Longer & Uncut." Considered more offensive than cocksucker in that it is a bit more graphic and calls the person a bastard, implying that the person either was born out of wedlock or is of questionable moral character.
"Shut your fucking face, uncle fucka!
You're a boner biting bastard, uncle fucka!"
-Terrence and Phillip, "Uncle Fucka"

Jamal: "You're a cocksucker."
Evan: "Oh yeah, well you're a nobgobbler."
Jamal: "If you were a dinosaur, they would call you sucksalottacock."
Evan: "Well if your parents could name you again, they'd name you Isaac York-Hawk."
Jamal: "You spend more time on your knees than a Gregorian monk."
Evan: "Well you're a boner biting bastard."
Jamal: "Come on man, that was uncalled for."
Evan: "Yeah, I guess so. Sorry."
