When you grab your flaccid dick and flop it back and forth saying "peek a boo" in a hugh pitched voice every time you flop it.
Used as a mating call for your nearby lover, a request for a blow job.
"Peek a boo. Hey baby, I'm floppin' a peek a boo for you. You should put it in your mouth. Peek a boo . . ."
When a couple who enjoys pain takes a pancake with syrup and hits the male in the testicles until he cannot take it anymore
Joe said to his wife let’s get to flip floppin tonight baby
When you drink too much and get sloppy drunk or start floppin' around, usually black out drunk from cheap liquor or 4 lokos
Husband -Damn babe you were floppin' out on 4 loko
Wife -fuck I flopped out last night
