If you quickly survey today's cafeteria offerings, you give them a once-over. After this swift once-over, you'll probably order the pizza again, like you do every day.
Once-over is an informal noun, a great way to describe any brief inspection, search, or examination. When you're signing a contract, it's smart to read it carefully rather than just giving it a once-over. But when you're choosing a piece of Halloween candy from the basket your neighbor is offering, it's fine to grab one after a once-over. This American English slang term was coined at the beginning of the twentieth century.
