Do you know any websites that introduce common English expressions?

[Ted T]

Hello, I'm learning English as my second language.

I want to learn many short English expressions that are often used in conversations such as :

Anything goes.
Can do.
Anything you say.
Are we square?
Catch you later.
Are you for real?

It is easier to memorize these short sentences because they have only 2 or 3 words.

Do you know any websites that introduce these expressions so that I can get hundreds of these common expressions?

Or is there any way that I can get these expressions from somewhere like books?

Thanks for your advice.
