The way the number Eleven will be pronounced in the near future. It will also completely redefine being a teenager. When someone turns Eleven(teen) they will be considered a teenager. Then once they turn twelve they will be considered a kid again, reminding them of who they are. Then once they turn 13 and become a teenager again they will be completely ready for it and all and any problem associated with being a teenager will no longer exist.

2) Any number of dubious merit.
3) An adolescent who has not finished puberty who attempts to be taken seriously by acting like someone who has, though most frequently, this act is obvious and leads to be taken less seriously.
