When recieving oral from your partner, you tell that bitch to close his/her eyes and open his/her mouth (making him/her believe you are about to blow your load) then you turn around and expell vile ass fumes into your partners open mouth.

A type of fart that is done while sitting, the one-cheek sneak is done by leaning to the side to let the gas excape. Very handy when sitting on a smooth, hard surface while wearing shorts, to prevent "hovercraft" sounds.

the act of quietly squeezing out a fart when sitting down by leaning to the side slightly and raising one cheek.
My girlfriend always knows when I fart because even though I do the one cheek sneak, I always give it away with my farting facial expression. Not to mention that the room also smells like a fucking animal died in there!

A George Carlin joke: You lift one butt cheek and muscle out a small fart. It would usually sound weak, unless you powerhouse it. Best for church.
Kid: Oh man *lifts one cheek and lets out a small fart*
Preacher: mmmm, sweet Jesus.
AFTER CHURCH
Kid: I call that one the one cheek sneak.

The easing out of flatulency gently, usually when sitting down, so as not to attract undue attention.
