Etymology

Origin of icebreaker

An Americanism dating back to 1810–20; ice + breaker 1

Explanation

An icebreaker can be an exercise or game that's meant to introduce people to each other in a fun, relaxed way. You know the first day of school, when you are asked to share your favorite stuffed animal — that's an icebreaker. If you invite party guests who've never met, you might play a game or tell some jokes as an icebreaker. A more formal icebreaker could involve games or songs that help people remember each other's names, for example. In this metaphor, the "ice" is the tension caused by being in an unfamiliar situation or meeting new people. The original icebreaker was literally that: a ship designed to break through ice in frozen channels at sea.
