A mixture of the insults "bonehead", who is someone who is stupid, dumb, or just slow, and "douche bag".

It has recently been used as the title of an episode of the Fox show Traffic Light.
Ben: You're dog just shit all over my yard!
Joe: Yeah, dogs poop sometimes, what are ya gonna do about it?
Ben: Hey, listen ya bonebag! I shouldn't have to pick up YOUR dog's shit!
