KOSC 

Keep Our Scene Clean. It's a campaign started by the PLURR Semi-Sober Ravers from all over. They don't mind the drugs that go on at raves, as long as the people doing the recreational activities are being responsible about it.

on myspace or plurspace you would put KOSC next to your display name to show that you like to "Keep The Scene Clean"

Koscheck eye 

The act of GSP (Georges St. Pierre) jabbing someones face until their eye swells up like a vagina during/after a good clitoral pumping.

The man recieved a Koscheck eye for making fun of GSP's accent.

Koschecked Out 

An automated nervous system response; resulting in the display of an injury from a phantom strike.
In the animal kingdom; this is the equivalent of "playing dead" - right before discovery, that in fact - you are alive and unscathed.

UFC 113 when Paul Daley threw an illegal knee that clearly missed only for Josh Koscheck to act like the strike landed, this would be an example where he "Koschecked Out".

koscophleeghsion 

Koscophleeghsion is the feeling you get when you are with a good friend or family member and start to have deep, intense and philosophical thoughts together.

Last night at 3 'o' clock in the morning, Diego and I went into koscophleeghsion.
