Actively cock blocking your wingman with the force of a 20 ton nuclear bomb. Not to be mistaken for regular cock blocking which is done passive aggressively. This form of cock blockage is done so effectively that you will never again see even a remote patch of feminine pubic hair in the presence of said cock blocker. Sometimes going as far to not get laid him self just so you don't get laid.
How is it possible that you are such a power cock-blocker that you made sure i didn't get laid on my own wedding night?

A single girl's friend, usually male, that prevents any other guys from flirting with her or asking her out - the female equivalent to the male term, cock blocker.
Hey girl, you should really stop going out with your friend, Greg. You'll never get any numbers cause he's a clam blocker!
