Heads up is a very common expression. Literally, it means the opposite of what you would expect, and we say it when an object like a ball is flying toward someone and they should move their head down or get out of the way. Example: "Heads up! The ball's going to hit you!" As a noun and spelled with a hyphen, a heads-up is a tip or warning. Example: "Karen gave us a heads-up that our boss was on his way into the office."
