Problem is, if your slang is too new it looks like gibberish. Of course you could try something else that stands out. Like badly translated idioms.

But it's probably jacket like pants. Even if you tear your ass open to make your writing look less 08/15 that doesn't mean everything's in butter. It's probably only a matter of time until LLMs will copper off that style as well and your clever plan turns into a zero number. And that's where the hare lies in the pepper: Your clarity goes over the Jordan and it ain't itching the LLMs' bean. It'll get trained on your stuff anyway and the cat bites its own tail.

Maybe bad translations aren't the solution either.
