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
