Diverse town in southern California, mostly famous for Camp Pendleton, the marine base, and the San Luis Rey Mission.

Oceanside can either be really nice or really ghetto- depending where you live. The more well-off people tend to live in Ivey Ranch, Mission Mesa, Fire Mountain, Ocean Hills, and the homes near the El Camino Country Club. As for Deep Valley, Eastside, South Oside, or Tri City...well, those are the areas you want to avoid late at night.

Oceanside is actually very beautiful, and contains a nice community college, MiraCosta, an old drive-in theater in The Valley, a country club, a bike trail, a mission, and several bars and businesses along Coast Highway. Great place to visit.
I'm bored, what should we should do?

The worst yet most expensive place to live in Cali. Oceanside is famous for Camp Pendleton where U.S Marines are stationed.

The shittiest beach town in all of California. Don’t bother going to downtown Oceanside, all you will see is druggies and marines wearing high and tights, and tan backpacks. Where everybody is either a marine, a spouse of a Marine, a retired Marine, or is related to a Marine some how. Everybody resents marines.

Home of the worst Mexican food and simoan gang bangers. Don’t buy a car off the Pacific Coast Highway. Also, avoid the purple church.
‘Hey man, let’s go hang out in downtown Oceanside, California tonight’

Oh fuck that place, I’m not trying to see boots’

Where one consistently jacks off into a shot glass and drinks their own cum because they can't get laid by dudes or chicks.
Male 1: Hey, you're cute what's you name?
Girl/Guy2: Hey there, not to be rude but I'm just not interested, I'm looking for a real man.
Male1: Oh thats alright, I'm just going to head home an Oceanside Oyster night cap.

Later that night...

Male 1: I love drinking my own cum.

The place to build a family if you are poor, white, Trump supporters or poor, white public school teachers.

-It’s the only place I could afford in Long Island that is still mostly white.
