N.N.S.
Nasty Nate Syndrome is when a guy takes a dump in your butt and pees like it's a concert and he's the lead singer.
He peed in my hair. I had to go to the store and buy a new hat.
My friend got it in the car. He screamed and got out.
My brother got it in the hallway. He ran out and didn't come back for an hour.
