Racits is a very serious, easily contracted STD. It can be obtained through oral, anal, and vaginal sex, as well as through raping someone with your eyes. Symptoms include: a bright green rash on your elbow in a shade reminiscent of the Great Gazoo's pee, loss of armpit and pubic hair, stretching of the earlobes, swelling of the pancreas, diabetes, and cancer of the tailbone. If you think you have any of these symptoms, you should immediately go get tested at your local clinic, as it is potentially fatal.
