STSMFU 

Shut The Stupid Mother Fuck Up !!

I never claimed it was cool. It's just something I say when I'm a little more pissed off (especially at the phony vatos making up ignorant shit as if a ghetto definition.)

PHILLIP: "Aarghhh, another dick cheese fake ghettoism! STSMFU! Must kill!"

PHIL'S CONSCIENCE: "Chill, Phil."
