Tweener 

a "tweener", in Canadian Folk Festival (and other music festival) circles, is the person who entertains, on mainstage, during the set-ups, between the headlining acts.
originated by C. McKendrick, Winnipeg Folk Festial Media Crew

Rory McLeod's tweener on Friday night mainstage, blew the crowd away. Sometimes the tweeners are better than the headliners.

Tweener 

When a male polishes some nipply nipples that are cold with their pointer finger and thumb in a rotating fashion in order to perform a generous, warming, humanitarian service to a female. Usually performed on females that are cold, of whome are wearing t-shirts that reveal the soldier like stance of the nipple. Any slapping of the face is a sign of encouragement towards the action(they love it!)

I think she's cold, let's do our good deed for the day, as our scout master told us, and give her a tweener.

same as the "taint" but funnier 'cause not everybody uses it and some people don't know wtf it is.

The skin between the genitals and the chocolate starfish.

On a mountain or BMX bike:

I was nose heavy on that last hit and my seat hit me right in tweener!

Man, I love it when your girlfriend licks my tweener.

People who are sexually intimate with when they are both between relationships - similar to friends with benefits, but with the expectation that while the friendship will continue, the benefits are put aside when one of the people involved gets involved in a romantic relationship.

When I'm not dating anybody seriously, I call my tweener to see if he's single too.

TWEENER (n.) - a dyke who has feminine features, mannerisms, proclivities, etc., but cuts her hair short and dresses butch in order to secure her lesbian identity. Connotations: the look does not suit her; she is insecure

She's just come out, so I think she's going through a tweener phase. She keeps buying Dickies and a-shirts, but talking about how she misses high heels.
