A face that certain people will use to cover up their sexual and creepy jokes.

The 10th letter of the Greek Alphabet, but only fucking nerds use it for that. It really is a word that is synonymous with Just Kidding (jk)

It's most likely origin is from twitch.tv, where it is most commonly used.

Another origin that I know about was on a Minecraft Server Network called Project Ares (Now Overcast Network) back in mid-late 2012. The different servers in the network were based off of the Greek Alphabet, and kappa.oc.tc was the last server added to the network before it's revamp. Somehow, it caught on, and people started spamming it on the forums, and it was given a meaning.

When you joke make a embarassing/stupid joke, just use kappa and it will all be ok !
