Get the O my Godmug. A half breed libtard who’s best version of talking smack is fantasy football put downs. This type of spineless grown ass man deletes messages that are at his expense because he feels it commands respect to be a dictator.
Man did you see what Austin did?! He tried running his mouth and when a few other guys came back at him he deleted their messages and locked out their trash talk abilities. He’s such a Commish-o-cunt!
