once upon a time someone was gifted the wolf name “moon moon” from a werewolf name generator thing, and the reaction was hilarious.

Here’s a screenshot of the original post:

Moon Moon then became a full on meme:

Basically anytime a wolf or dog acted weird, people would go “goddammit moon moon” and it was a fun time. I’m explaining this very poorly but basically it’s an ancient meme about a wolf.

Fenrys got dragged into it because

a) his animal form is a white wolf and

b) his last name is Moonbeam

So Moonbeam + wolf = moon moon
