I'm going nut fuck, Yeah they know this! Suspended in time I have an extra guy inside... my dick. But you no need, I know'd it, learn this, I got pigeon wings tatooed inside my eyeballs! Dude smoke my fresh haircut! I got sexy nipples, spewing roots, uh yeah! I got butts that turn into trucks! I make money growing extra limbs for aliens... that abducted me! But those space bucks never work in any store... I can never get those minutes back!
"A person with an eccentric personality that has used shit loads of narcotics over their life, resulting in a swiss cheese brain effect that lends itself easily to OCD and other psychiatric disorders.
