Break the ice
Break the ice means to warm up an uncomfortable situation. To start a conversation with a new person or people.
Asking about some one’s interests is a nice way to break the ice. “Did you have a nice weekend? What did you do?“
“Everyone at the party was very quiet, finally Jim told a joke and broke the ice. After that people began talking to each other.”
