A-class Warrior
The jock in gym class who thinks they're the best, but they're just trying too hard to impress the teacher and show off like a total idiot.
He tried to beat me in the 50-yard dash and failed. He's just a gym class warrior.
She did push-ups until she turned red just to show off. Total gym class warrior.
He did the mile run and collapsed. Still thinks he's the best.
