how do we describe girls that pretend to be cute?

I think the word "cutesy" would do. You can use the word to describe boys too. Any person or thing.

One word that might best describe this is "coquettish" - a wonderful French word. The noun is a "coquette" and is basically defined as a girl who seeks to attract men but isn't wanting to be affectionate to any specific person. It is a little similar to the word "flirt."

Siggy

thank you but flirt is not what i'm looking for.

so i just say someone is so cutesy, that's it? I mean could you give me a sentence?

thank you

Hi,

If you want to avoid slang, you might say 'coy'.

Best wishes, Clive

You should use this word when you find this person or thing annoying. You must not use this word in an approving way(it isn't a big sin if you did).

If you want to be rude
You can say "She is such a cutesy so and so.

If you don't want to be rude:

You can say "It is almost sickening when she tries to be that cutesy choozy-

GoldenIf you want to be rude
You can say "She is such a cutesy so and so.

is this related to the Teen Squad?
so and so

This so and so is not related to Teen Squad.
So and so is used instead of an offensive word.

It's very grateful to exlpain in such detail,

will you go a little further and give some more examples of how to use "so and so" and "choozy-whuuzy "(in a internet forum)
