KK is typically used as a shorter way of typing okay cool (k kool). Although some people look down on people who type this way, it doesn't really mean anything other than the person typing doesn't have enough time to type the full thing (especially in online FPS).
Player 1: Meet me in the base
Player 2: KK. Be right there.
The superior way of saying 'k' or 'ok'. Can be used as a substitute for either.
person a: hey i'm having a party at my place tonite if u wanna come
person b: kk i'll be there
The best known definition of 'kk' is: Ok, cool alright.
But when a dutchman (somebody from the Netherlands) says 'kk' it means kanker, wich is cancer in English.
You should not use 'kk' when a dutchman can read it, because he could start raging.
In Swedish "KnullKompis", meaning "sex buddy". Ie, a friend who you sleep with without getting romantically involved.
Vi är inte ihop, vi är bara kk. Translation: We're not together, we're just sex buddies.
