The kk acronym simply means "okay" or "message acknowledged." 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 other Internet lingo, kk might also be heard said aloud in person, as "kay kay."

Most of the time, texting abbreviations like this are meant to be lowercase, like lol (laughing 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.

History of the KK Expression

The little bit of history behind kk relates to the 1990's expression "k, kewl." 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.

The kk expression, like many other Internet expressions, is now part of online conversation culture.

How to Use KK in Text Messaging

You can use kk in any way that denotes your approval or acceptance of something.

  • "Hey! I'll be there in 15 minutes" -- "kk"
  • "I should probably go to sleep now... kk?"
  • "I'll be late to work because of this mile long train!" -- "kk, that's fine"

Other kk Meanings

KK is also an abbreviation for "confirm" in the aviation context.

In some languages, it means entirely different things, like "month" or "machine gun" in Finnish, or "kanker" (cancer) in Dutch.

Others use the letters "KK" as slang.
