tween 

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!

tween 

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.
