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.

twenteenager

A twenty-something who still acts like a teenager: still lives at home, parties every weekend, drinks energy drinks mixed with alcohol (see: FourLoko), thinks excessively about themselves.

Also see: twenteen

The cast members of the Jersey Shore are total twenteenagers. I just want to punch them all in their collective faces.
