12 Year Old

An age where kids don't want to be kids, even though pricing at movie theaters and most restaurants says that still are, and their mentality is child-like.

"I wanna seeeejqp Innn da Miggz, one TWELVE." Wiggadawgshit sticks out his chest, showing he is NOT a child. "One twelve" is the way for a 12 year old to order a child's ticket...

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

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

12 year old

A person that isn't 13 yet. Even though they might be better than you at some things, they're 12 and not 13 so you can make fun of them. They're 12 and not a teen and you can have fun with that anytime you want.

12 year old: Hey, wanna watch a movie?
Teen: Dude, it's PG-13...
12 year old: But-
Teen: 12 YEAR OLD, HAHA!
