1 definition by STAN.

one who incessantly prevents a male from getting any kind of action, while not actually engaging in any sexual acts her/himself, probably due to a severe lack of self esteem. or because he/she wants the cockblock-ee for her/himself but wont admit it. in general, a douchetastic, two faced blonde.
The Blonde One is a cockblocking prude.

the ONE fat chick that is ALWAYS freinds with the sexy people- while she never gets any action herself, she feels compelled to block as much cock as humanly possible because all the freinds turn to her for advice. for christ's sake. someone bang the fat girl. please.
