The act of mobbing and robbing someone as you furiously masturbate thinking of a sexy Asian maid. It has to be in a period of no less than 10 minutes. At the end one must cum in the victims hair, disragarding the victim's sex
"hey dude Shawn got a dirty Cesar from an anonymous bystander, he is in therapy now.". "hey let's roll tonight at the bridge doing dirty cesars to innocent bystanders."
