look up any word, like blumpkin:
The ancient art of cock-blocking yourself. This can be anything from what you say, to what you do around a female you are interested in. Basically, any self-sabotage that will take you from getting a girl, to getting nothing.

Generally done whilst out drinking in a bar/club, but occasionally it can extend to choices made whilst sober, like canceling a date to go out drinking with mates, or saying the wrong thing whilst out on a date.
