a kappa is a japanese water monster.

the kappa has a beak, webbed feet and a shell on its back and dwells under bridges, pouncing on any who attempt to cross the river. The kappa also has a bowl-like head, in which it keeps a small amount of water, and this is a key to apparently defeating this monster. when you are confronted by a kappa, your only hope is to make it bow to you, thus making the water fall out of its head and draining it of its power. strange, no?
here we are in japan. oh look, there's a river we must cross. good lord! a kappa! quick! make it bow to us!

The main symbol/emote of Twitch.tv. It represents sarcasm, irony, puns, jokes, and trolls alike. If you see this term used outside of Twitch.tv, then this is not the correct definition. Usually used at the end of an ironic or sarcastic sentence. Sentences that contain a Kappa should not be taken seriously. If you search "Kappa Twitch.tv" in Google you can see what the emote looks like, and why it is used as it is. Sentences that use Kappa do not always have to make sense.
You hold the speedrun world record of this game, but I bet you'll die on level 1, Kappa.

A Japanese water spirit. It looks like a human/duck/turtle type of thing. They live in ponds and rivers and drag people in and drown them. They also pull your intestines out through your behind. A Kappa has a dent in it's head that is full of water, this allows it to go out on land. Also, Kappas are very polite. If you come a across a Kappa all you have to do is bow to it, the Kappa will have to bow back spilling the water on it's head and leaving it powerless. Kappas also love cucumbers, toss a cucumber into the water were a Kappa lives and it will not harm you.
People also portray Kappas as being very cute and innocent looking. These versions of Kappas are indeed irresistibly adorable, they make me want to squeeze their little Kappa heads off!
And yes, I am aware there is also the Kappa Kappa Gamma sorority who think they're so elite because they've been around for so long. Well the REAL Kappas have been around since ancient times, drowning you and feasting on your soul!

Me: Omg! Lookit the ickle Kappa!!! Ah, wait! Omg no, not the colon!!!! *Tosses cucumber*

Sorority chick on Urban Dictionary: Omg! This definition says a Kappa is a Japanese duck thinger! Omg they're dishonoring our almighty elite-ness! *Gives thumbs down to definition*
