The H stands for 'hentai', the Japanese word for pervert(ed) and what many people call anime porn. Also, 'ecchi' is the way Japanese people pronounce H and you'll find that some people refer to hentai as 'ecchi-stuff' as well as 'H-stuff'
doesn't it mean ecchi? because Japanese pronounce "H" in English the same way. It's like an abreviation...isn't it? Mimiru
ecchi is the same thing. I've hard from animes that are in those categories use them differently in a sentence but still meaning the same thing. the person going to do "perverted" stuff.
you might find this dumb but.... I know what "H-stuff" refers to, I mean I've seen it a lot but what does it actually mean? hentai? horny?
