Tweener 

An acquaintance you sleep with in between serious relationships. The tweener has no long term potential.

Are you still seeing Chris?
No girl, he was just a tweener.

tweener 

In an episodic series (comic book, tv show, etc.), an episode in which nothing significant happens, but that is necessary to bridge the gap between the episodes that come before and after it.

I was all excited that the newest issue of my favorite comic hit the stands today, but it was a total tweener. What a drag.

Tweener 

A contraction of the words in between.

1) It is an item or person that is in between two things.

Examples: a) Something that is small between two larger things. b) A person stuck in the middle between two sides of an argument.

2) The middle person of a threesome.

This task to do at work is a tweener. We don't have to do as much work as that large project, but it is not a simple job either.

Jane is always the tweener of that threesome.

That tweener wants to lick Justin Bieber's tweener.
