What's up with Larp ?

I'm only mildly chronically online and I've noticed the uptake in the usage of larp as an insult or something I think ? In online spaces.

It feels like it came out of nowhere and I don't get it because it's used in contexts where it don't make sense.

I understood it back in the idea when people had said it like "some white people come to black spaces to larp as a black person" cuz I've heard people talk about like "as a black man" and things like that.

But the word is suddenly being used in ways I don't get. Is this one of those things like Karen or Unc where when it becomes mainstream people twist the meaning ? Did someone identify what the new meaning is now ? Cuz I cannot figure it out. Is it a new word for poser ?
