The act of having intercourse with a middle aged chinese-black man that foams at the mouth (A common sign of rabies). It's only considered being "Orc'd" if the man has one wart at the base of his penis and goes through flop sweats as he ejaculates.
Timothy: Dude, I got Orc'd for the first time last night!
Samuel:I remember the first time I got Orc'd, did he break out sweating?
Timothy: Oh yeah, a ton. But the sweat dripping from his chin felt good on my back, but it got even better when he came. It was like Icy/Hot on my back.
