Your Definition
Idiomatic expression; English. Definition: When someone says something and once it's heard, it breaks your preconceived notion - e.g. you can never "unsee" or "unthink" it. When someone "smashes the mirror" you can see something for what it is or think about something in a new way counterintuitive to the previous way of thinking.
