Nicknames for really cool people, that are a little messed up in the head sometimes, with the letter K beginning their name. Although the person with the nickname "Special K" is cool (and probably okay at xbox), the person who nicknamed the person "Special K" is the cool sauce ultimate. Another nickname for a person already nicknamed "Special K" is runt and caramel.

Slang for Ketamine Hcl, a dissociative anesthetic used in medicine on both humans (typically in young burn victims) and animals. Also used at lower doses as a recreational drug with effects similar to those of PCP or DXM (though Ketamine lasts much shorter). Typically insulfated or injected intramuscularly.

otherwise known as ketamine,k. special k is a dissociative that can either be snorted or injected into the muscle. it makes you unable to control your body like a tranquilizer would. what it does on the mind is another story. it sems like you enter into a different world were you dont understand anything that is going on.
eg a friend of m ine didnt understand what she was meant to do with a chair. ie what way she was meant to sit on it.
