Niner Syndrome is when freshmen come to high school and think they're the shit, just because they were the seniors back in middle school last year. Niner Syndrome can result to an unnecessary boost in ego, thinking you're the shit, talking to everyone like you're bigger than them, thinking you're the most important person around, etc.
Alex: Dude, what's with all of the Niners this year?
Dave: They have Niner Syndrome.. but a nice initiation should be the best medicine!

Any of the chicanos, kinfolk, or of the few woods that either grew up or reside on the Avenue, that don't take no mess from no one. True hustlers, money makers and grind artists, that take care of their peoples and only have love for those that have love for them.
Female1: "Girl, we 'bout to go to the south side and hook up with some real G's."
Female2: "I heard that girlfriend, ain't nothing finer, than a *one niner*"

A group of the most rabid, extreme, and hostile fans of the San Francisco 49ers. Along with having a massive number of followers, the members of the Niner Empire are very aggressive, and vocally abusive to opposing fans, and debunk the myth that all 49er fans are wine-and-cheese fans. Home base is Candlestick Park, where they gather at every 49er home game. The Niner Empire is also made up of many different smaller factions, including fans from all over the nation and even world. There are Niner Empire groups from L.A., San Diego, Arizona, Washington, Minnesota, and many others, including the core Bay Area group, that founded it.
The Niner Empire is always out in full force in fierce loyalty known only to the 49ers. Rival fans like wussy, bitch ass Raider fans, and gay ass Cryboys aren't welcome near The Stick, and will be taunted, yelled at, and have things thrown at them for being gay. Seahawks and Rams suck ballz too. THE NINER EMPIRE-EXTREME AND HOSTILE.
