Blue Brain 

Chronic Marijuana User. So named for the habitual indulgence in pot smoking, edibles, tinctures or any dispensing method has turned the lining of said users brain blue. Characterized by being jobless, lacking personal hygiene, slow unintelligent speech patterns, sedentary and sloth-like, impotent and therefore useless as a human. Energy of any kind being dispensed by individuals is rationed for "weed outages" only. Prone to rage and individuals known to be "Blue Brains" should be avoided if weed isn't present and or available. Irreversible.

I'm sorry I'm late for work, the "Blue Brain" giving me a ride locked himself inside the car and couldn't get out.
