What is Flab Fuck?
1.
masturbating into the excess fat of an adjacent passenger on a long flight--this may happen while one is asleep (nocturnal emission) or awake
the dude gets off the plane and the person picking him at the airport says 'oh shit, how'd you get that stain on your shirt greg? you must've gotten flab fucked. that's not the way to get to the mile high club fuckwad.'
Greg had been asleep the whole time and hadn't noticed, plus it had dried up by the time he got off the plane.
