ball or peen 

A parlour game centring upon a man who has located an ambiguous part of his genitals in his grip, and then prompts the many spectators encircling him to decide whether the flesh in question hails from his scrotum or his penis. Bets are arranged and money thrown onto the ground before finally the genitals are revealed to be either 'ball' or 'peen'. The game resets and during the anxious wait for a new presentation of genitals, the chant "BALL OR PEEN" is sounded by the spectators.

"BALL OR PEEN! BALL OR PEEN! BALL OR PEEN!"

The genitals are revealed.

"Five bucks that's scrote," Anth ventured. Nathan demurred and accepted the challenge. "It's dick for sure."
