You know what bugs me? Caucasian anime fans who like to refer to each other by using each other's names as if they were written in Japanese. That is, "Albert" becomes "Arubaato", or "Dickface" becomes "Dikkufeesu". Bloody hell, that annoys me.
I'm not saying that switching names between languages is necessarily abhorrent. People do it all the time, for very good reasons. Consider the massive Asian community we have here at UW Math. Without a Romanized representation of their names, they could have never had library cards.
I'm talking about people with very English names who speak very English English. And now I'm talking to them, so listen up. Your names, they are English. They are not Japanese. You are not Japanese. Every time you call each other by your Japanimated names, purely because you really like anime, I want to freaking shove my foot through your ears into your brains, because it's insipid and annoying and very, very stupid.
I think I'm going to invent a language where all the syllables are vicious self-deprecations and create a fad around it, just to make a point. See how much fun when they call up a friend with, "hey, is I'm-a-nasally-defecating-she-monkey-with-a-gripping-lust-for-my-uncle's-saliva-pool-that-collects-in-his-navel-and-every-now-and-then-when-I-masturbate-my-genitals-run-away there?"
