An autoimmune disorder triggered by a mutation of the CYG-G7 genome resulting in a giant inflamed pussy the size of yo mama.
Symptoms: itchin n burning, phat-gargling pussy, smells like teen spirit and cigarettes.
Treatment: there is no known cure for the devastating disease of pterodactyl pussy. Sufferers have been known to find relief by feeding their pussy peach flavored yogurt and crushed ice cubes.
