Sacky Clappy 

The action of two males having sex with one female, one in the vagina and the other in the arse. While this happens, their balls hit each other repeatedly resulting in a Sacky Clappy.

My friend has not spoken to me since we did a Sacky Clappy with Stephanie.

Sack Clapping 

When a man is fucking another man and they are going so hard their ballsacks are clapping together. Only straight on Tuesdays and if you have socks on.

Guy1: my balls hurt so much!
Guy2: why?
Guy1: I was sack clapping last night with my homie

Guy2: that’s gay
Guy1: I had socks on so it cancels out

Crappy Sack

Crappy Sack is a game identical to hacky sack except you can play with any sort of object EXCEPT a traditional ball or hacky sack. The most common objects used are empty beer cans or keg cups. Other objects can include, but are not limited to: crumpled up paper, wallets, bottle caps, and cell phones.

If you are playing with several people at once and the crappy sack makes it around to each person without hitting the ground, a Crap is achieved and everyone rejoices. Not an easy feat when plastered.

Person 1: You guys want to get a round of crappy sack in?
Person 2: What the fuck are you talking about??
