Young people between the ages of 18 and 21 that have adult liability, but not adult status. Example: can be drafted, can be incarcerated, can enter into contract, no longer subject to parental control; but, cannot admit ones self to a hospital with co-consent of someone 21 or older, cannot consume alcohol at all or be in an area designated over 21 only.

A sudden (not very long lasting) phase or trend that kids from the ages about 10-14 are generally interested in. Tween Waves interest people who are in the stage when you are too old for toys but not quite mature for anything else.
Guy 1: Have you heard the new pop-band Fighting Daisies?
Guy 2: That's too tween wave for me. I'm 21.

The escalating sound produced by a large group of tweens. At first, the sound is a light chatter. Then it grows in intensity and the frequency changes to a squeal. Eventually the incoherent ramblings of these little pricks drowns out all ambient background sound until you get a massive migraine.
After my buddies and I walked out of the movie theater we noticed a large group of tweens waiting around for mommy and daddy to come in their BMWs & Lexus to pick them up. Their tween spastics were so deafening that we started to bleed from our ears.
