I think Kay Kay meaning OK. We sometimes quickly say K instead of OK when responding to someone.
Gosh.My son does this stuff:
"kk"
"Alr" (alright)
"nm" (never mind)
🤦♂️
Thanks for the explanation; much appreciated.
That sounds almost like a new language to me.
And yes, I know, I know, language always changes and evolves, and the young always coin, or invent, fresh forms of slang that are impenetrable - and that is the point - to their elders.
