51.
Accomplished Cock blocker:
When this guy walks up, he says "CHECK IT!" and like a bull, body slams you out of the way, with his gargantuan neck roll, in order to get next to a Pump,(a female - his words)
He flexes and raps for a bit (always flexing), and then without reason - Just leaves.
You think he's gone – But, oh no, like being hit by a train, the madness starts all over again.
He returns, body slams you again and continues on his quest for rejection.
When confronted, like a Chameleon, he changes colors and tries to redeem himself by flattering you in front of the Pump..Not meaning a word of it.
Later, after he's sober, he will make excuses and try to persuade everyone around him that he did nothing wrong and that he is the victim.
This is also the guy, when cock blocked himself, immediately declares "COCK BLOCK!-COCK BLOCK!" at drop of a hat and announces it like Chicken Little or the Town Crier.
This is the worst kind of Cock Blocker.
Sean - "Here's to you!" Heavy weight Champion and Accomplished Cock Blocker.
