SAN MATEO. pretty much the bombest place to be in Bayy Ara. Home to drifters, rich white hoes, druggies going to ivy league schools, irish pubs, hot-cheeto eating mexicanos and a few blacks/asians. Pretty much divided up into two sections...one side of the freeway is gangstaland (bayside midd school, college park, fiesta gardens) and theres the white Baywood freaks, burlingame BIS kids, the sexy centrals...other shit. Most of the gansta's hang out Downtown San mateo on Friday nights outside the theater. Hell yeah.
Damn she's hella beaner...probably from Bayside in "San Mateo".

Get the San Mateo mug.
Coolest part of California just a little west of San Francisco. Home of the Hillsdale Knights!!!! Also home to the Aragon Dons (boo) and the San Mateo Bobcats (real creative guys). Also home to a bunch of middle schools, including Abbott, which even if you went there, you can agree sucked.

Half of the population of San Mateo think that they're super ghetto. Someone should inform them that they don't live in Oakland because nothing bad ever happens in this hood. We're super sheltered.
San Mateo is the coolest part of Bay Area! Repping 650!

San Mateo is divided into 2 gang areas The West Side (aka West Madtown or West Madeio) home of the WST (West Side Tongans or just the West Tonga Mob which are basically the tongan bloods) and and the Northenos (aka Northes or mexican bloods) and the other side is Shore View (aka SV or ESSV = East Side Shoreview) which is on the East and Northside which is home to the T.C.G (Tongan Crip Gang) and the Suranos (aka The Scraps or mexcian crips) They have wars between races. Most of the northside is white kids the south which is Hillsdale and Los Prados (aka LP) where the fake northes are and the faggot white kids are and in the hills the whites.

San Mateo is a medium-sized city just south of San Francisco. It rocks. The city is the home of many famous people, including Patriot's Quarterback Tom Brady.
San Mateo is way better then P-Town and R-Dub combined.

A City of 93,000 people in the San Francisco Bay Area. It has 3 public High Schools: San Mateo, Aragon and Hillsdale. By far, San Mateo High School is known as the best. Their mascot is the Bearcat, which is hella cool. In Mateo (as it is called by Locals) hella is common slang. Tom Brady is from Mateo, and went to Serra, a private religous high school, also Merv Griffin and Alicia Silverstone are from Mateo, both attended the best high school in the area, San Mateo High.
Mateo High's colors are Orange and Black, and Orange is a cool color, fosho'.
I was in my car cruisin' down 101 North, and I passed by San Mateo on my way to the San Fran Airport.
