Deaf people - 258 (very interesting) and 84 (there’s no good direct translation for this)
Huh, I had never considered deaf slang before. Is there somewhere to read up on this?
Hmm, it’s hard to think of good resources for this. It’s just kinda part of community. You could google asl slang and look around in YouTube or something. Or learn asl (or your country’s sign language) and join the community.
Found a link with a short quip about 258 lol

I don’t get the 258 and 84 one, also deaf.
258 = very interesting. 2 being v, you sign “very”, and then using 5 into 8 from ahead of your face/nose area for “interest” sign.
And for 84, try and sign it kinda side way. Kinda like “terrible” sign, but you would say it after crazy or whatever happened.
Like “oh really? 84!”
Ah then it’s prbably one of the sign languages, mine does not do it like that.
I was referring to ASL, what’s your sign language?
