Viscant is another Marvel player (who actually won MvC3 at EVO) that Phil has history with.
He challenged Phil to a money match at EVO, and Phil responded by suggesting they fight IRL (yes, really, a FITE ME IRL).
Viscant, who actually had some amount of fighting experience (boxing or martial arts idk), accepted and was dead serious about beating the shit out of Phil. Phil would posture as if he was going to go through with the fight for some time, even suggesting that they sign documents to prevent legal action if someone got hurt.
At some point Phil realized how serious Viscant was, and of course was scared shitless. Phil would ask Viscant to pretend that they were going to fight, but instead do DX crotch chops. Viscant told Phil how fucking stupid his idea was and declined.
Viscant eventually dropped the whole thing once he realized how scared Phil was of an actual fight.
Yet another example of Phil talking tough online, then showing what a true little bitch he is in real life.
