How Do You Say Beans...?

Would you say... A.) "Cool The Beans" or B.) "Chill The Beans"?

If you've never said this before then don't bother answering and do something else.

It doesn't matter if you don't say it anymore, but if you were going to say it... What would you say?

Please answer A "Cool The Beans" or B "Chill The Beans"?
