Definition: a basic introductory meeting, often informal, where you meet a person (or people) for the first time
Examples:
This is a new customer, and we’ve never met them in person. Let’s schedule a short meet-and-greet, so we can introduce ourselves.
We didn’t do much at yesterday’s meeting. We have a new CEO, and it was basically just a meet-and-greet. He talked for a few minutes, and then it was over.
