Where did dogwifhat come from?

I'm genuinely curious, could you please explain the origin of dogwifhat? I've been hearing about it lately in the crypto circles, but I'm not quite sure where it came from. Is it a new project? A meme? Or is it some sort of inside joke? I'm really interested to know its story and the reason why it's gaining so much attention. Could you please shed some light on this mysterious entity called dogwifhat?
