cock block

Someone who has, will, or wants to prevent a friend/random person from getting laid by a member of the opposite gender. Also, when a person knows he's not getting a piece of tail will do absolutely anything, best friend or not, to make sure nobody gets a pice of tail by the end of the night. Someone who will convince a member of the opposite sex to go home, instead of going to a party they were really excited about, by telling lies to prevent any others from having a chance of getting lucky.

When Kyle, John, and Boy Blue were chilling at a karaoke night, John invited a girl to com to the after party. On the way to pick up boy blues truck , Kyle was guranteed a piece of tail, for she was licking his ear. After Boy Blue had gotten his truck, Jenn decided to go with him. He then convinced her to go home, by telling her that Kyle and John were bad people. Steve IS A COCK BLOCK!!!!!!
