A kid or teenager who lives in a crowded urban area where a high level of crime is common, and where the stereotypical types of people are easily seen.
George is a city kid. He spends all day watching his back and he takes public transportation. He also makes sure he does not draw attention to himself.

Jimmy is NOT a city kid. He flashed a 50 in a classmate's face, only to get jumped right after school by the Bloods.

a bitch from nyc, basically Manhattan aka the upper east side, that thinks being from NYC is tuff
they live in million dollar apartments and townhouses
and are all around fags
a classic joke is making fun of ppl from yonkers and white plains, saying "u guys are from upstate,haha"
how is that a diss?....idiots
city kids expect doors to be held for them and lack common sense because they are used to having their business men fathers and nannys do everything for them.
it would be humorous to see them venture outside their bubble of 14th st to 96th st...

Kids that live in cities, and are obviously to young to buy the game and get their parents to buy it for them on Christmas or their bday, they are obnoxiously annoying, and are the biggest noobs. They like to brag about having sex with peoples old mothers. They all have the same high pitched cracky voice and chances are you will get one in your lobby every game. They often have scores like 2-24 yet they still think they are the don.
John: Ahahaha look at all these fucking city kids.

Jason: Yea it's going to be an auto-lose if we get them on our team.

City kid: "Aww fuck you bitch, I fucked your mother, ohhh, you aint never gonna have sex, NOOOB We da best MLG pro snipers ever, we gonna fuck uuuuuu. pro shit yo. (very high pitched voice)

A reference to a song by the same name from the band "O Pioneers". It was originally used to describe a place filled with hipsters who will continually judge you.

But it was bastardized and now it is used to describe something that is very awesome.

It can also be a group of people who are very righteous
"I'll never fit in down in Cool Kid City"

"Oh man, that righteous item you have there is totally Cool Kids City."

"We are Cool Kids City."
