The true definition of a 909er as follows:

Someone from the inland areas of Southern California from the cities of Riverside, Corona, etc (Area code 909 - recently changed to 951 but you are all still 909ers in my book).

These Southern California beach invaders drive their overly lifted trucks or SUVs to the point where they themselves (probably compensating for their height or size of their dick) can walk under. Their "sick" vehicles are often covered with stickers that say "So Cal", "Metal Mulisha", "Skin", "SRH", Iron Crosses, and various other stickers that only look cool to them.

Their appearance entails the 'perfect' beach attire: shaved heads, bent upward billed hats, wife beaters, sagging dickies, high black or white socks, and shoes(worn on the sand), bandanas, white sunglasses, and shitty tattoos (nautical stars, tribal bands, barb wire, sparrows, and last names written in old English) how creative.

You will most likely find them in groups, starting fights, feeding lame pickup lines to girls, or in their stupid lifted truck blasting awful music. They also make fun of locals because their own insecurities will not allow them to see past their Dragon Sunglasses. Sadly, these events increase dramatically every year.
True Story...took place in Huntington Beach, CA

Darren: (upon sighting a group of 909ers) "fully clothed at the beach huh its like 95 degrees out"
909ers: "what? what did you say..(draws a line in the sand) I DARE YOU TO CROSS THIS LINE BITCH!"
fellow 909ers: "yeah! yeah!"
Darren: "haha wow did you really just draw a line in the sand? such a douchebag"

Low life pieces of garbage that reside in the Southern California areas with the area code of 909 and 951. The area code 951 was created the same reason doublewide trailors were made, because even white trash runs out of room.

The trashiest 909ers live in Hemet, Perris, Moreno Valley, Lake Elsinore, Temecula, etc. All of these people drive lifted trucks with dirt bikes (aquired by high interest loans) in the back, have Skin or the latest Freestyle Moto-X brand sticker on the back, a guy driving with a bandana and shitty tattoos in a jersey or wifebeater, a anorexic blond haired slut who has slept with a high percentage of other 909ers (who is a single mom at age 14), and loud music with the windows down at any temperature of the day.

Most of these people know they are worthless compared to the entire populous of the world, but they have a hidden hatred towards the beach cities crowd. They tend to talk shit about people more fortunate to live by the beach due to the higher quality of life, cooler temperatures, and lesser amounts of homeless and people who wreak of filth. The 909ers typically say how nice it is in the 909, and that they would rather live there than in places such as Orange County and Los Angeles. This furthur proves the point that 909ers are completely oblivious to the fact they are less intelligent and completely ignorant when it comes to life, and anything for that matter.

Most 909ers buy big homes for low prices due to lower property values and a shittier way of living. Hemet owners can buy a 3500+ sq ft home for the same price as a townhome in nicer areas; but are surrounded in section 8 housing communities, strip clubs, meth labs, prostitutes, hot trash, poverty, and overall disgusting situations.

909ers have to travel outside the 909 to have decent healthcare services, cooler temperatures, better schools for their children, and the ability to breathe without a respirator.
909er: You live in Orange County?

Normal Person: Why, yes I do

909er: Temecula is SOO much nicer than Orange County

Normal Person: You are a complete loser, and stop trying to steal my wallet, you piece of garbage. Go back to your meth lab in Hemet

A loose term used to describe a person that's anywhere from the Inland Empire, despite the fact that the 909 is considered San Bernardino. The 909er is the absolute worst enemy of Orange County residents. There are many variations of this undesirable specimen, ranging from bros (a dirtbiker) that wear high black socks, drive a lifted truck if they have a vehicle at all, smoke methamphetamine, get in brawls with random kids walking down the street because they are "emo" while simultaneously listening to emo music themselves, yelling obscenities at random people walking down the street and much, much more. They often claim to hate "niggers" but can often be seen listening to shitty rap music at parties drinking plastic bottle vodka (charcoal filtered tamirnoff) that they stole. There are many other 909ers such as the white power skinhead 909er, they are often seen with "IE" tattoos, they enjoy smoking methamphetamine, breaking into houses and going to prison for pissing dirty at their parole appointments. They can be seen with their Mexican "baby mommas" despite the fact that they are for racial Aryan purity. There are also black 909ers who while despite looking like your average crip or blood from Los Angeles are much, much more worse.

909ers can often be seen looking for recycling/aluminum cans with lights on their heads similar to the type that gold miners wear.
I had a glass beer bottle on my porch and and a 909er stole it.

Someone who drives a lifted truck but is probably 5 feet tall with a motox sticker of some sort on the back with tatoos of the trendy star, most likely wearing a bandana around their heads to be extra cool.
909ers are so trendy they should stay home

Worthless idiots, pure and simple. This word describes pretty much every White and Latino guy under 30 living in the desert areas of SoCal. Insecure rednecks who think they have to look and talk like a thug in order to get respect. Most of them are skinny. If they work out they never hit the lower body. Wear oversized T-shirts in order to hide being skinny. Whatever the shirt says, it's usually written in Gothic font, along with some kind of iron cross for thug-lyfe authenticy. Wear flat-billed hats with a logo having something to do with bikes even though they've never owned or ridden one. Their version of "dressing up" is to keep wearing whatever they were wearing before, except throw on a thick gold chain and half a bottle of cologne. Always stand with one of their shoulders slouched, because it makes them look "down with the struggle". Criticizes everyone who lives at the beach, to make themselves feel better about living in a boring 110-degree smog trap. Half of them use, manufacture, or sell meth, or wouldn't mind being mistaken for such, since it would make their boring life appear more hardcore.
909er: Everything you said above is true.
