: Where did the following phrase come from?

: "Be there or be square"

A 'square' is a person who is ordinary or conservative in behavior or demeanor, not 'cool' or 'in.' The writer is saying that if you are not part of the scene or the action, then you are not cool. I think this is relatively new in usage, but I am unsure of the origin.
