It's going to be OK.
You know how to be polite - "Mom, Dad, I'd like you to meet my boyfriend, So-and-So". They are curious about him, they will most likely lead the conversation.
If your byfriend has anything in common with either of your parents - a sports team, a hobby, a tv show - you could mention it. "by the way, Dad, So-and-So is a big Yankees fan", or whatever.
But your parents will know what to say, and you don't have to have an hour long conference. Just a quick meet and greet.
It's cool - they just want to know who it is their daughter is spending her time with - you will all do just fine, I promise.
