1. Noun A disease that usually afflicts nerdy, awkward social outcasts. If you contract this disease your social future may be in immediate danger. Outward signs are sometimes hard to notice, but include the following:

1. Constant touching of the penis.
2. Frequent and uncontrollable masturbation.
3. Frequent and bulging erections.

If you think you have contracted Hancock Syndrome, there is no need to panic; the solution is relatively simple. Remove your hand from your pants and leave your house. Find yourself a female, and convince her to have sex with you.

Extremely wealthy area of Los Angeles run by a bunch of Free City clad, rambunctious teenagers who know how to party. Larchmont is the heart of Hancock Park, otherwise known as the HP. At night, Larchmont is filled with 11 year old skateboarders in front of blockbuster and druggie teenagers with cold hard cash burning a hole in their pockets at Pickett Fences, LF, and Spirituali.
