Katanna 

A girl who is every bit crazy but is a amazing friend. Don't mess with katanna or she will most likely mess up your face. Katanna's are a rare breed and if you can find a girl as amazing as her then your lucky because there is no one better at being a friend . Katanna's are usually red heads or brunettes and are extremely pretty and have beautiful eyes. She is adventurous and isn't afraid to go cliff- diving or parachuting. She looks danger in the eyes and couldn't be more brave. She also is the best person to take to a party. If you can find a katanna then you are a very lucky person.

Person 1: Wow did you see that girl beat the sh*t out of that guy?!

Person 2: Yea that was katanna.

Katanatard 

A person who unquestioningly believes any (or possibly every) myth, no matter how incredulous, about the cutting power, efficiency, design, manufacture, materials (typically the steel) and other attributes of the katana (whether an artifact or a replica), especially in the hands of a samurai, ninja or some other action hero. Typically, the katanatard will also feel the need to make similar extravagant claims him/herself to everyone else (especially any skeptics), in spite of a typically superficial knowledge at best of militaria and military history. Often also a japanophile, sometimes also an otaku, and possibly, but not necessarily, also someone with a sexual fetish for the katana.

Origin: Blend of "katana" and "retard", probably modeled on "fucktard" and similar words with -tard as the second element.

I heard this one guy on the boards go: "European plate armor? That's the best you can do? Please. An Edo-Period katana could cleave a Sherman Tank in two." Damn katanatards these days...

Chainsaw Katana 

The most powerful weapon in all existence. It has been known to cause multiple emotions in humans, the two most common being fear and sexual desire. It is thought that chuck norris himself crafted this destroyer of worlds. Photographs and drawings of the divine weapon must have an explosion photo shopped in the background so that the paper doesn't burn up from the awesomeness.

Man 1: Did you hear about that planet exploding the other day?
Man 2: Yeah, must have been a Chainsaw Katana
