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.

twenteen

The age between nineteen and twenty-one. Twenteen is used when the birthday boy/ birthday girl is not excited about no longer being a teenager and feel like if they mask the age behind a false definition, the pain of getting old will lessen.
