Chat room trolls who, despite the fact that they are in english speaking forums, insist on using the japanese names of
everything. Frequently found in
anime forums, claiming that the true and ONLY name of Full Metal Alchemist is actually Hagane no Renkinjutsushi, for example,
even though it is quite the mouthful for non japanese speakers.
Nihongo
Nazi: WTF noob, it's Hagane no Renkinjutsushi, not FMA.
Baka! You just called Kaubôi bibappu, cowboy bebop... man what a
lamer.
Reader: What a nihongo nazi.
