I'm such an angel at work, where do I release my demons?

I'm such an angel at work. Polite and PC as fuck. I can't stand it anymore. Where do I go to release my darker self? I want to be vulgar, insulting and let my aggression out. Been flaming on a few Facebook groups but got kicked out (not using my real identity of course). Fuck this. Can you suggest where I can find fellow flamers and keyboard warriors to fight with (virtually of course). Thanks and fuck you!
