a couple of (people or things)
Two or more people or things. The phrase is intentionally vague in number. It's not going to be a big party—I just invited over a couple of people from school. I just need a couple of minutes to talk to you about your upcoming schedule, sir.
couple of
two; two or three; a few; some; not many. Bill grabbed a couple of beers from the refrigerator. I hung a couple of pictures on the wall.
