What is the real name of a DOGE?

Excuse me, could you please clarify something for me? I've been hearing a lot about the term "DOGE" in the cryptocurrency and finance world, but I'm not quite sure what its real name or origin is. Could you tell me what exactly DOGE stands for? Is it a shortened version of a larger term, or does it have a specific meaning behind it? I'm really curious to understand the background and significance of this term in the industry. Thank you for your help!
