When one, or a group of people, show up at a party not knowing anyone, become the life of the party and the centre of attention, then disappears into the night never to be seen by anyone else at said party again and leaving everyone to wonder who they were.
Emily: Hey who were those people at my party?
Libby: Not sure, I think they were Chevy-Chasing it last night.
Emily: That's a shame, i can't remember their names, but what a Chevy chase they were!..
