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.
