pee on your nuts

A figurative term meaning to have a small penis. Usually used as an insult.

Tough guy #1: "I can bench press 275. What's up now?"
Tough guy #2: "Whatever man, I can clean 200!"
Tough guy #1: "Well I can do 20 pullups!"
Normal guy: "All right guys, quit arguing about whose dick is smaller. At the end of the day, you both still pee on your nuts."
