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!!!

Get the Twenty-tweens mug.
The first three years of the second decade in the 21st Century, i.e. 2010 through 2012, to describe the next generation.
As a child of the 80's, I loved Nintendo, Glam Rock, and all things John Hughes. However, the children of the Twenty-Tween (20-tween) generation are watching bad remakes of great 80's movies and television and profess their love for Justin Beiber, Taylor Swift and the Twighlight Saga.
