A word used by vocabulary nazis, meaning the act of fluffing a pillow with flatulence so that the person about to sleep will lay their head down and smell ass.
Man 1 says, "I'm about to go to bed."
Man 2 runs ahead of Man 2 and hits Man 1's pillow with the flatulent fluff.
Man 1 goes to bed and as soon as he puts his head down, he says, "Ewwwww. Why the hell does my pillow smell like ass?!?!"
Man 2 laughs.
