I think the "joke" is dumb AF and I don't like it. But I really like the phenomenon where people get together and start shitposting with a certain theme. It brings people together, creates a sense of community and encourages posting. This is something Lemmy very much needs.
I feel like a lot of (especially new) Lemmings are like the dogs that don't want to give up the ball, no give only throw. Lemmy needs to grow and expand. If everyone forces it to be something it isn't it will die.

Thank you, she's been trying to lose weight recently
