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.

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.

Teen: Dude, it's PG-13...
12 year old: But-
Teen: 12 YEAR OLD, HAHA!
