They do it in Japan, and if you imitate a Japanese person in any way it's offensive.
Never mind that that's just an expression people sometimes make during intense sex and the Japanese just happen happen have a word for it. Never mind that it's just an ANIME PORN TROPE, hardly something respectable worth defending, and people glom onto retarded trends all the time. Because it is a stereotype in manga or anime or whatever, imitating Japanese porn is perpetrating the stereotypical submissive Asian womon myth through mockery, probably with a side of cultural appropriation.
Basically, it's Japanese sexual blackface.
