A cock blocker is a close friend of your target who perceives your disgusting intentions re her close girlfriend. Her intention is to block your battle plan, thus preserving the apparent chastity of your target -- or in this day 'n' age -- preserving the lady's opportunity for her own not-so-pious intentions.
During a splendid evening of ice skating, and Just after I had copped a really awesome 'fee'" as well as the mother of all sloppy smooches, her roommate shows up and wants to leave early. So I bellow at the top of my lungs: YOU GODDAMN COCK BLOCKER!!1
