Slingsack 

When one pulls their own scrotum to the point of maximum elasticity, then releases their sack unleashing a high velocity flesh attack at a target.

“I was face fucking this girl last night and she starts using way too much teeth. I had to pull back and hit her with a good slingsack. Bet she never does it again”.

Sinsackencum 

When a man commits some type of sex act that is not only illegal but a sin as well and is able to finish what he started by ejaculating inside of or on his victim.

The pastor of the Catholic Church of sister Mary was extremely horny, so he took the alter boy into his office so he could empty his ball sack. The pastor committed an act of Sinsackencum!

SlingSchlong

A wiener so long, one can use as a replacement slingshot if need be.

As David and Goliath fought, his slingshot was broken. He used his Slingschlong to defeat Goliath. Thus, David was made King because of his insane wiener.
