The less attractive of the two. She'll ruin your approach, flow, and groove. She will stand in the way of you making your move. Insert your best friend to run interference for a couple of plays. Get some and then break up with the girl saying that you don't want to see her anymore because of her annoying friend. Problem becomes solution.
John blocked the cockblocker so I could knock it with Cheryl. John ditched the cockblocked after eating all the candy bars that she had in her purse. I got laid and then broke up their friendship (for her own good) and now it's Saturday.

Cock is another word for penis & normally when you 'block' something you are either stopping something, or preventing something from happening. the term is normally used when you a preventing someone from having sex.
