fartpalm 

When you facepalm with a hand you just farted on. Useful in analysis of the fart's contents. Especially potent when wearing knitted gloves or mittens.

I just fartpalmed and now my nose is burning. I have got to lay off the 4-alarm chili.

Ugh, dude! That's nasty. Fartpalm on your own time dude, not while i'm trying to enjoy my nachos!

To fart into the palm of your hand and quickly hold it up to a near person of disliking.

"Dude! Did you see Peter fart palm Taylor over there!"
