What does ni idea mean?
Expression
no idea
Said on its own, with no verb, and it closes the question completely. The long version is no tengo ni idea and the vulgar one no tengo ni puta idea, which means exactly the same at higher volume. Said this short, it carries a note of indifference: I do not know and I have not wondered.
—¿A qué hora empieza? —Ni idea.
