big idea

Ambitious central notion

A big idea is the central concept or thesis behind something—a campaign, a book, a business proposal.

The phrase often carries slight skepticism or challenge: So what's the big idea? demands explanation for questionable behavior.

What's the big idea, showing up at midnight?

In creative and business contexts, the big idea is the core insight that makes everything else work.
