Square Up 

The term "Square Up" is also used specifically by sex-trade workers (prostitutes of both sex) to describe "going straight" ie. retiring or otherwise getting out of the business to live a normal, "square" lifestyle (with spouse, kids, mortgage etc.) up off the street.

The hooker couldn't take the street life anymore so after one of her johns proposed marriage, she decided to square up.

Prudy Square

Someone who is both prudish and square. Its immature sound is deliberate; it may very well be used by younger people, or people who act younger than they are.

It may be a generic insult as well; in other words, the person this is directed to doesn't necessarily need to be a prude nor a square.

British in origin.

"Stop being a prudy square, Neil, and do the shopping!"
