n. The act of farting into a pillow, piece of foam rubber, or sweater, and then sneaking up behind someone and pressing into their face. A particularly vile prank after eating spicy, exotic food.
My cousin Flobert was being a little bitch, so I saved up a greasy taco fart, grabbed a cushion from the couch, and totally Nigerian Ambush-ed him.
