When someone becomes a teen. 13 year olds think they're amazing, but instead they have raging hormones and their face is covered with zits:
1. a young teen
2. horny
13 year olds like to hump each other and inanimate objects because they think it's not masturbating, but it really is.

Somebody who is insulted, called an idiot, called a ball of hormones, called an annoying little kid who does stupid things, by almost every definition on the urban dictionary.
It's totally unfair how 13 year olds are insulted on the urban dictionary.
