A Chilean slang phrase used to refer to a very long and indefinite period of time, similar to 'once in a blue moon'. It implies that something happens very rarely or probably will never happen.
Examples
- Spanish: Juan dijo que iba a limpiar su cuarto, pero eso ocurrirá el año del loly.
- English: Juan said he was going to clean his room, but that will happen once in a blue moon.
