Is Cryptomania a real game?

Excuse me, could you please clarify something for me? I've come across the term "Cryptomania" and I'm wondering if it's actually referring to a game, or if it's just a colloquial term used to describe the intense fascination and obsession with cryptocurrencies? I'm genuinely curious to know if there's a game out there with that name, or if it's more of a metaphorical expression. Could you shed some light on this for me?
