six going on twenty meaning?

[shinem]

What is the meaning of six going on twenty about a little girl?

 

[Ouisch]

It means that although she is a child, she either acts or dresses like someone much older.

Thank you very much

Ouisch has given the meaning. The idiom (well, not really an idiom as it doesn't always us those numbers - it's more of a conventional piece of wordplay) is based on the traditional use of 'going on', in expressions such as 'six going on seven' [=reaching the end of his/her seventh year/well over six - in fact nearly seven].
