the gay/queer equivalent of jock block wherein a homo who's trying to get some action either gets blocked from the same or who's embarrassed by a so-called friend and prevented from hooking up.
i was chatting this hot guy up at a club the other night when richard jock blocked me by coming up and asking me if (my rash had cleared up) or (am i still living with my parents) or (did you get a job YET?!)--of course the hottie excused himself and got the hell out of there!
