People that oftentimes get defensive about their age because of the stereotype given out on the internet, and try to act more mature then they actually are to make themselves seem not as bad

(in an attempt to seem different from other 12 year olds) "im 12 years old and this is not funny"

12 year old 

A cancerous kid who acts like a badman, listens to stormzy and Lil Pump and wanks to Fortnite porn. For example in the uk 12 year olds can be seen riding around in packs with their BMX wearing man bags and saying fuck/fucking in every sentence. The best way to identify a 12 year old is to look for a midget wearing Nike or Adidas tracksuit and with their hair very short on the sides but long on top.

However these are only the apex 12 year olds. The other type is more innocent, they play Minecraft, Roblox or Fortnite and suck off their teacher at school, they will snitch on anyone who doesn't respect the rules.

I don't play Fortnite anymore because 12 year olds have taken over.

12 year old 

horny cosplayers. Also the age where puberty starts to kick in, its not a good age, at this age you get access to lots of apps on the app store or play store, also at this age you start to think you are so mature even though you are really just a underaged horny little shit
at this age you already know multiple things your parents rather you don't know and you also become dirty minded, you have a huge friend group or are socially awkward and you have an unhealthy obsession with not doing your work and sleeping most of the time
you don't go out that much either

12-year-old 

This a type of boy can be found in the Call of Duty community with a K/D of 0.34. Once a 12-year-old is threatened, or insulted, he proceeds to tell you that he had sex with you mother, calls you gay/queer, he often calls you a fag. One would often challenge you to a 1v1 snipers only. If you are challenged, DO NOT LOSE THE FIGHT! If you lose the fight, he will proceed to insult you and make fun of you. If you ever run into one in a call of duty lobby or a game, the best thing you can do is roast him. He will usally stay quiet, try to roast you back, or rage quit the game

I fucked your mom
Just cause you don't have one doesn't mean you need to be 12-year-old
