It may seem strange to wish someone to break a leg, but it actually originates from theater traditions where actors believe that saying \”good luck\” before a show brings bad luck.

3. \”Piece of cake.\” – When someone says that something is a piece of cake, it means that it is very easy or simple to do. This phrase might confuse non-native speakers who take it literally.
