Deaf people - 258 (very interesting) and 84 (there’s no good direct translation for this)
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 probably a different sign language, mine does not do it like that.
I was referring to ASL, what’s your sign language?
