the new age for a person who doesnt want to lose being a teenager once they hit the age of twenty!

1. The default beliefs installed when you were a child.

2. An unexamined position you absorbed from your environment growing up.

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.

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.

The age defined by a person who can't move on from their teen years. Mostly used by people who are in denial that they are actually twenty.
