An effeminate homosexual who is usually on the receiving side: often biting the pillow in pain or pleasure. Also enjoys giving head (swallows of course).
Another word for pillow biting: rough anal sex. Typically a phrase describing the act of man-on-man gay sex, doggystyle notably; where a guy is on all fours and is getting pounded in the ass, the sheer force and agony of this is causing him to bite down on the pillow.
Particularily good sex, especially with a very hot male. Taken from the book "Breaking Dawn" in which case a hot male, Edward Cullen, has particularily good sex and bites several pillows in the process.
"So, have you 'done it' with Enrique yet?"
"Yeah, we've been biting the pillow all week!"
"Oh, my God, he is so hot!"
"Yeah, I'd bite a pillow with him."
