Fartsandwich 

When you flatulate into the palm of you're hand, close it and proceed to cover a loved one's mouth with your fart hand. Thus, asserting the fart smell onto their lips and ultimately, into their mouth.

Eugene: FARTSANDWICH!
Frederick: Oh man. not again! This one taste kind of good actually.
