Super Secret Cool Kid's Club

If I told you, you'd be banned from the club.

(It's for cool kids only. Super secret. Only one in every ten million are in.)

"Yo dude are you in the Super Secret Cool Kid's Club? I want in"

club of cool 

The club of cool is a defunct group of nobodies who wanted to be somebodies on an internet forum. They believed vbulletin's karma system and post count to be some sort of e-penis indicator, and set about trying to inflate said e-penis, showing up what true fuckwits they were.

Imagine the lamest group of people possible on the internet. They clump together, and become elitist, believing themselves brilliant. That is the club of cool.
