weebsplain
when a weeaboo loudly corrects and explains things about Japan, often inaccurately, to a real Japanese person. (like mansplaining, but instead of a man to a woman, it's a weeb to a Japanese person)
“Samurai did take their katana out for other reasons than bloodying it, Derek. Japan is humid. Blades need sharpening. So shut the fuck up and stop weebsplaining.”
