A girl from the age 10-13. This is the age where they grow out of toys and get into boys and makeup. These girls often have self esteem issues and have lots of drama in their lives.

an unfair label for any person who is between the ages of 8 and 12/13. it is an insult to be called a tween. if a person is above the age of 11 they should be refered to as"young adult" or just plain teens. most tweens are labeled as being to young for being a teen, but too old for being a kid, although they act like it. thats bull cause all they want to do is be old enough to drive a car so their parents will stop giving them a hard time. REAL TWEENS ARE THE PREPS WHO LISTEN TO POP AND LIKE PINK AND TEXT TALK MORE THAN NECCESSARY. the other 12/13 year olds who play it straight and dont really fit in anywhere are tyically the cool ones so dont mess with them.
REAL TWEEN: omg i cant wait to listen to the jonas brudas l8er!!!

Other: what the hell just leave me alone

To be tweening it one must gave spent over 23 hours on any given game in under two days. This phrase can be used to mock, however it can also be used to describe one's own actions.
Did you hear about Eric? He spends his weekends tweening it.

Or

I just spent my entire holiday tweening it on Borderlands the pre-sequel.

Or

James : You're such a bangout Andrew!

Andrew: Nah, I'm just tweening it.

A child aged between 10 and 12, the definitition originally only applied to 12 year olds, but has since broadened.

TWELVE + TEEN = TWEEN.

Someone who is not quite a teenager.

Often watches Disney shows (Hannah Montana, Wizards of Waverly Place) and listens to Disney bands (Jonas Brothers, Miley Cyrus/Hannah Montana).

Can be used in a derogatory fashion, implying that someone is immature.
Ex 1:

"My sister had her tweenage friends for a sleep over last night, they stayed up listening to Hannah Montana and watching High School Musical."

Ex 2:

Girl 1: " I love (insert celebrities name here), I want to marry them and have their babies and...
Girl 2: You're such a tween.

Coming from an 11 year-old girl's point of view, this is what a tween is.

This word mostly used to describe an 9-12 year old girl who:
-watches Disney Channel religiously
-wears more makeup than most adults
-uses excessive profanity while talking to friends, because they think they are a teenager
-only wear clothes from Justice
-gossips about what will be forgotten the next day
-either hates the latest pop boy-band or loves them, there is no inbetween
-desperately tries to be a teenager
-tries to act emo, scene, hipster, etc.
Example one:

Tween One: Oh my fucking gosh! I just lost my fucking lip-gloss!! It's the end of the world omg!!
Tween Two: OMG!! Hope you're okay! Tough luck!

Example Two:
(Texting)

Tween One: OMfG!! DiD u Here dat (Tween three's name) goT 2 go 2 da 1D consert!?!

Tween Two: OmFG!! ShE Dosent evin Lyk them! FaKe Fan Alert!1!!
