Wet Wilkie 

Like a wet willy, but when you shove your dick in someone's belly button.

Mary: I got a wet wilkie, it was terrorising rape.

Stairclap 

When you're running down the stairs very quickly in boxer shorts, and the weight of your testicles causes your scrotum to move against your gooch and make a loud clapping sound.

John: Ew, Mike. Yesterday I was running down the stairs and I did a stairclap. My mom heard. She looked grossed out.
Mike: EWW! DUDE, I DIDN'T NEED TO KNOW YOU HAVE A NASTY STAIRCLAP!
