Tweetyween 

Tweetyween is an international festival where Tweetybirds are praised. In certain cultures there is a tradition of dressing in creepy costumes that look like little birdies. The preparation and consumption of so-called "Tweetywiches" is also a very common ritual, especially in Frankfurt am Main. The popular Tweetyween festival takes place on May 27th every year.

"Happy Tweetyween!"

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.

twenteen 

Essentially a replacement word for Twenty, however, this is more of a characteristic of defining the new "kidult" age. Which is the age from 18 - 25, where people are staying at home longer, in order to obtain an education without moving out. Also used for people who continue to be a teenager well after their age has exceded the teenage years. This covers the ages from 20, through to 29 (twenteen-nine), as the age of 30 becomes thirteen, which is going backwards.

I am currently twenteen (20) years of age. Actually, I am currently twenteen-two years of age. But that is so not the point.
