1. once in a blue moon
Definition: very rarely, not often
Origin: When a full moon occurs twice in a calender month, the second
moon is called a blue moon. This occurs very rarely.
Note: This expression is very informal
Sample: My boss is pushing me at work. Once in a blue moon,
I can get a day off.
ps: we have two blue moons this year, do you guys know that? :P
2. out of the blue
Definition: suddenly, from nowhere, without any warni |
