What is Kappa: The meme has become a sort of patron saint of light hearted trolling among the gaming community. Users typing Kappa into Twitch chat see a special emoticon featuring a smug looking human face.

In the early days of the video streaming website Justin.tv, before it was rebranded as Twitch Interactive, an employee named Josh Kappa worked there. Josh's face was uploaded as an emote named "Kappa." Its popularity grew, and Kappa became the main symbol/emote of Twitch.tv. Twitch users use the emote to convey sarcasm, trolling, or simple mischief, and sentences ending with the word "Kappa" should not be taken seriously.

Twitch used to have an employee named Josh Kappa back when it was Justin.tv. Kappa the monochrome face received popularity for being synonymous with either sarcasm or trolling and they kept the emote after he left.

Kappa is an informal name given to the picture of Josh Kappa, a former Twitch (then called Justin.tv) employee captured in greyscale where the man casts a look of utter sarcasm. It thus denotes any statement that inflicts sarcasm.

An example – "It was the most kappa moment of my life" therefore means it was the most sarcastic moment of speaker's life.

Kappa, also known as 'Greyface,' 'Trollface,' The brand ambassador of Twitch' etc. is in my opinion an icon of the gaming world and the most popular emoji used in Twitch Chat.
