What is dogwifhat used for?

Excuse me, I'm just a bit curious, but I've come across a term called 'dogwifhat' and I'm not quite sure what it means or what it's used for. Could you possibly explain it to me? I've heard it mentioned in the context of cryptocurrencies and finance, but I'm not entirely sure how it fits into the bigger picture. Is it a tool, a service, or something else entirely? Could you elaborate on its purpose and functionality? I'd really appreciate it if you could help me understand this concept better.
