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!!
Tween One: LOLZZ I hEARd heR PaReNtS Got divorSed!! LOLZZ FUKIN LUZeR

An age set overlapping preteens, 'tween 8 and 14. A tween desperately wants to be a teen, but isn't about to stop being a kid. May flirt one minute, but be embarrassed about it the next; usually prefers titillation by proxy.
When I was in 4th grade, several of us would gang up on a boy and girl and make them kiss each other for our titillation.

I was standing in line behind another teen, and the 10 year olds she was baby-sitting kept pushing her against men behind her to to get titillation by proxy. I made sure to stand behind her a lot that day.

Google "CSM Models" for an eye full of tweens getting titillation by proxy, flirting with the camera instead of a person.

Someone aged 11, 12, or 13 years old....basically in between a child and a teenager.
Most tween girls try to act like teenagers, but are still very childish.

term used by animators, particularly those who use that bloody picky and irritating program called Flash, to describe movement or transistion from some weird thing to another. Used in phrases such as 'motion tween' or 'shape tween'. Derived from the word 'between'.
Joe: What tween should I use if I wanna move an object in Flash?
Tom: Use a motion tween dude!

One of the stpuidest words ever made up to describe a person aged 10-13. Another word for the space between the anus and genitals, you would rather want to be walking around labeled as a "Pube." Another word for tween is tweenager.
Tween=Inbetween

Wow, that's pretty damn clever.
