Akin to a weeaboo except focused on martial arts instead of anime. They take themselves very seriously and probably believe they need to have their hands registered as deadly weapons.
Similar to a Weeaboo, someone who is obsessed with Mexican Culture, etc. and attempts to act as if they were Mexican, even though they're far from it. They use Mexican words but usually end up pronouncing them wrong and sounding like total assholes.
A weeabu is a person that is completely, and I mean COMEPLETELY obsessed with all aspects of Japenese culture, all the while, not having any acsess to Japan, at all. They are simalure to otakus, but have a life outside of home.
Joe is such a weeabu, all he does is talk about anime and Pocky. (Please note that I do not know any "Joe's" in my life, so please do not take offense.)
