a mommy guard
A mom who saves her son from a beating like he's the chosen one. The kid thinks he's invincible and starts bragging and fighting you while his mom yells at you and calls the cops. The kid is a total loser who thinks he's cool but actually has no life and just plays video games all day.
You think you can beat up my son? I'll call the cops and let my dog rip your face off!
He's not even cool! He plays CODMOW 2 and thinks he's the best at it!
You're just a loser who thinks he's cool because he plays a video game.
