Get the 12 year old mug.
1.A kid that doesn't want to be a kid. Typically in 6th or 7th grade. They are babies in real life that make themselves look stupid by trying to act mature. To remedy this, they go on myspace, youtube, urban dictionary, etc. and act like gangstas. 50%of their vocabulary used is "Your mom.", while the other 50% is trying (and failing) to insult other people. They also masturbate alot.

2.The kind of people that pollute myspace, yotube, and other 13 or older webites, thus turning them into a pile of crap filled with wannabe gangsters and tantrum-throwing babies.
1.
12 year old: "I don't wanna be a kid mom! 7th grade sucks!"
Mom:"Watch your language young man!"
12 year old: *Runs up to his room throwing a tantrum*
Mom and Dad (simultaneously) "Heh heh heh! kids!"
12 year old: "YOUR MOM! WAAAAAAAA!" *fap fap fap*

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...

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
