What does it mean when someone says 'behave yourself'?

Answer 1

This is probably "Behave Yourself" and is used frequently in the South. It is usually said between friends and/or conveys a sense of comfort/familiarity with the other person. It simply means to stay out of trouble or "Don't do anything I wouldn't do". In Canada it can be a stern "behave yourself" if the person is out of line or a playful "behave yourself" if a friend is being a little naughty and you both find it amuzing.

Answer 2

Oh, dude, when someone tells you to "behave yourself," they're basically saying, "Stop being a wild child and act like a responsible adult for once." It's like a gentle reminder to not do anything too crazy or out of line. So, like, maybe tone down the shenanigans and try to act somewhat civilized.

Answer 3

It means stop acting like a wild animal and start acting like a civilized human being. Basically, it's a polite way of telling someone to quit their shenanigans and start behaving appropriately. So, if someone tells you to behave yourself, you better shape up before they give you a piece of their mind.

Answer 4

I believe it means that he like you, don't get into trouble?
