What is the definition of Lightbulbvirus?

A 'lightbulbvirus' is basically a term thrown around when someone accidentally discovers a brilliant idea, but the lightbulb itself just doesn't exist. It's like finding out you've stumbled upon a room full of candles and no bulb at all, except maybe a slightly dimmer one that says "This one's for the late-night thinkers."

Here's an unsettling example sentence: "After months of searching for the elusive 'lightbulbvirus', the team finally found it in an abandoned, glowing orb in a dusty, forgotten lab – and it was just a flickering LED."
