Flappysmack 

When you take your scrotum and put it over your penis, and have a gay midget smack it, while pouring syup over your body and listening to John Lennon.

"Wow man that was crazy last night!"
"Yeah, I really enjoyed that flappysmack, John Lennon is my hero!"

flapansmack 

The art of being destroyed falling off a skateboard - a successful flapansmack must contain slams at two different bodily angles or more.

Flapansmacks are highly painful to experience and as such are very much a spectator sport.

Also referred to as smackanflap, slapansmash.

Ooohhhh! Flapansmack! He isn't getting up from that!
