Twenteen 

An alternate word for "twelve".

Used by 12 year olds who are in a hurry to grow up.

12 yr old: Hell yeah I am twenteen! I'm finally a teenager!

19 yr old: Being a teen is really not all it's cracked up to be. Slow down and enjoy being twelve.

Twenteen

When an individual has turned twenty years of age but they retain more characteristics of a teenager and don't fully accept the idea of being or becoming an adult.

Tom just turned twenteen, still an idiot.

Twenteenager 

Someone in their twenties still behaving as in their teens or who hasn’t let go of their teenage years.

Ken hasn’t accepted they’re in their twenties yet, they’re such a twenteenager.
