When your feelin' this chick and you spend most of your time together at the party/bar/house, but then some guy buys her a drink/tells a story and steals her interest from you to him. So all your time you just invested into this one girl has been wasted by another guy, or Cock Jocked. Fckin' Sucks.
Sometime in the Fall semester of 05'...My boy Eric got cock jocked by this one guy who tried to steal his girl Emily by buying drinks for her. But the only way to fight him off is play him in his own game and cock jock the girl back. Chillin back at my place Erik said he did not get the girl but we checked her out on facebook and concluded she was mad doodie anyway.
