Twenty-tweens 

An alliterative and fun way to refer to the years 2009-2012.

Person A: Happy New Year 2009!

Person B: Yay! 2008 turned out to be quite a mess! Let the Twenty-tweens begin!!!

adult tweens

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.

It sucks, we can die serving our country, but under the law we are still adult tweens.

mid-teens crisis 

Refers to the sense of panic that occasionally surfaces in adolescents as a result of the feeling of not having done enough, whether it is regarding their academic or social life. Typically experienced around the ages of 15 to 16. Or, alternatively, could also refer to a feeling of worthlessness experienced around this age, but is not necessarily the result of depression.

Many teenagers experience a mid-teens crisis the summer before the eleventh grade as the reality of high-school graduation and preparation dawns on them.

"If I ever got a paper cut in the tweencho, it would really hurt; that's why I always wear underpants while handling paper products."
