One who cock blocks another from being able to engage with a woman in any social manner. Mostly referred to as a CB. Also refers to guys who are with good looking woman but shouldn't be. Guys who try to attract the attention of the woman you are speaking to.
I was Cb'd by this guy last night at the club. I was talking to this girl and he walked up offered to buy her a drink right in front of me! What a CB.
