Twenty-teens

The Twenty-teens are the years from 2013-2019. Noticed how they start off with the word "twenty" and end with the word "teen"?

"Man, The Twenty-teens were the most stressful years of my life!".

Twenty-Tween (20-tween) 

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.

twentyteens 

The second decade of the new Millennium.

When we had the 80's and the 90's, they were easy decades to reference. This new decade is a little harder. So, being the teen years, it's the twentyteens.

Tweenty 

Someone who is somewhere in their late teens through early twenties, when they know everything and are absurdly idealistic.

I can't wait until he is no longer a tweenty and not such a d-bag.
