Well things I learned from japanese, is stupid things, when senpai, san , chan, kun, sama is appropriate, or stupid words like kuma, isekai, neko, kombini, chickin, omurice, hai, lie, konpiūta, pan, douma ect, kuso, yeah learned a japanese swear word as well lol. I generally picked up words when translating anime titles, do it enough times and it becomes easier. Watched over 400 anime titles, you bound to pick up words, here and there. I don't I know why, but I quite like japanese and the culture in general, extremely polite and modest people, a few unintentional closet racists however lets not forget their absolute perv nature, to extend that they have female only train carriages, and other weird shyte their into, like idols, lolis, hentai. The only thing I hate about the japanese, is mecha, I FKING hate mecha with a passion, I can't stand that shyte.
