Most ghetto place on earth. Home to the most rapists and criminals in all of California. Second in white trash only to Riverside. Known for many homosexual residents.

A stinking overpopulated shithole in the North San Fernando Valley of Los Angeles. Like everywhere else in California, it's overrun with fat cholos in Dodger gear that drive around annoying everyone with their loud pipes, and blasting the woofers out of their shitty Hondas. The bitches are all fat frumpy dropouts with an IQ of 2 that curse like inmates and waddle down the street ready to bust out their 5th little gangbanger. I used to have a crush on a girl that lived here in college, but she turned out to be a carpetmuncher. Fuck this place sideways with a hot iron dildo, thank God I'm out of here in a couple of days.
"Sylmar is the nipple of the Valley. How did you get stuck here?"

"My car broke down."

"Oh. I'm sorry. Try the squirrel tacos, with a side of fat bitches."

A high school in the San Fernando Valley. On the North East side of the valley. People there are mainly "OK", by that I mean some act nice while others are just plain assholes and bitches. Even though its surrounded by a low income community, some people try to show off like their rich but they're just fakes. It's not how you would say an "academic achieving" school.Also Sylmar is the best at football and girls volleyball. Always beat San Fernando in almost everything. Overall to be honest I give Sylmar High School a 3/10.
San Fernando High School: "Were finally going to beat Sylmar!!!"

Sylmar High School: "Idiots, I just hope we don't get shot. Everyone got their bullet-proof vests on?"
