1. A crazy mothafucka and the best
cornerback in the game of football.
Open your mouth and I'll shut if for you real quick
2. Being a
complete asshole to an opposing player after a hard-fought game/ taunting an opposing player (shermaning)
ex: After being scored on for three touchdowns by a wide receiver, the player shermaned as he
taunted the receiver after his team came back to win
the great game. (
