icebreaker

Coordinate term: slushbreaker

The new college hallmates were awkward with each other at first, but after a game of charades as an icebreaker, they were laughing like old friends.

At the moment the curtain went up there had to be a lively ensemble number of principals and chorus singing and dancing, the traditional “icebreaker” that also covered up the noise of late-arriving ticket holders getting to their seats.
