It's the same as nodding in person or saying "cool," "gotcha," etc. It's common to see kk or KK as a text message abbreviation or when you're playing online games. Like some other internet lingo, kk might also be heard said aloud in person, as "kay kay." However, in some cases, kk can just be a mistake when typing the regular "k" in conversation. Given its meaning, however, a mistype like this is normally not corrected and will go unnoticed. Most of the time, texting abbreviations like this are meant to be lowercase, like lol (laugh out loud) or brb (be right back). If you type them in all uppercase, it can come off as if you're yelling, which can be confusing.

Translated, this expression meant "ok, cool," but was stylistically spelled otherwise. Undoubtedly, "k, kewl" also influenced the use of kk in today's online chatting.
