N.N.S.
Nasty Nate Syndrome is when a guy sticks his pecker in your butt and pees like it's a fountain in the middle of a park.
He peed in my backpack. I had to take it home and wash it.
My cousin got it during a sleepover. He cried and ran to the bathroom.
My brother got it during a video game. He didn't even notice until later.
