Add this to your lexicon…

Ok, so here’s the traditional definition of “cock block” with an example:

to interfere with a man trying to pick up a girl.

Mike is Hitting on a Girl as Bobby Yells Across The Room)
Bobby : “Hey Mike did you get your herpes medicine yet?”
Mike : “Man, why you always tryna cock block me?!”

But what do you call it when a girl is “cock blocked” when trying to pick up a guy? We pondered over this at the Cook Library tonight while we were supposed to be researching early music…and we came up with “twat blocked.” Hey, it’s an equal opportunity world we’re living in; now we girls have our own term to deal with sexual interference!
