Udderfuck derives from utter-fuck describing someone who is a real asshole.

Also used as an insult insinuating someone spending too much time in the barn milking bulls.

Or someone who particularly enjoys fucking a woman between her (cowlike) huge boobs.

Also is a nickname of a popular character in the Everquest II universe.
Yeah that guy, Shadow, is such an udderfuck!
