It's a good expression, but you're using it incorrectly. When I go to parties, i like to introduce myself. When it is difficult to start the conversation, when we don't know what to speak about, i often ask the person if they speak any other languages. To introduce a topic that two parties can discuss, is to 'break the ice'. The topic itself is 'the icebreaker'. Sometimes they don't speak other languages, and aren't interested in the topic. Then, I need another icebreaker!

Here's a good example of an ice-breaker: A guy and a girl went on a blind date. They were both quite shy and when they first met there was an awkward silence. After a minute or so, the guy plucked up the courage to say; "Well, all we need now is a giant penguin". To which the girl curiously replied; "Why?", and he said "To break the ice". ^^

Oh, I don't know why the system didn't work properly. There are some coincident sentences posted here but I don't know how to edit or delete them. Please kindly show me the way to remove them. Thank you!

Extra questions: Do you think the boys/men should start to break the ice? In a modern society, it’s getting more and more difficult to break the ice with the strangers, isn’t it?
