pillow-biter 

An exceptionally vigorous butt-pounding between men in the dorsal-ventral position, generally noteworthy for its combination of depth, force and velocity, such that the poundee is transported to an otherworldly, orally-fixated state of extreme "hurt-so-good" pleasure as to unconsciously bite down on a pillow, duvet, forearm, Jack Russel terrier, or anything else that happens to come with close proximity of his mouth.

Josie: Did you see Tom last night?

Johnny: Until the lights went out, then I saw stars.

Josie: Total pillow-biter, huh?

Johnny: Been spitting out feathers all day.

Josie: The Tomster sure likes to pound ass.

Johnny: One of his many charms.

Josie: Many?

Johnny: Hey now...

Pillow Biter

Someone who is receiving such a ridiculous anal pounding from a man's penis, a female with a foreign object such as a pole, or in many cases close relatives with shampoo bottles, that they choose to bite down on their pillow for some relief from the pain.

Pillow biting is looked down on in the gay community.

pillow biter

A slang and highly derogatory term for a homosexual male. It was likely inspired by the notion that a male engaged in anal sex would be face-down into a pillow, biting into it.

"I think it's about time that those pillow biters be allowed to get married. They have rights, too."
