Hentai slaps

Actually, hentai is not the correct term for pornography produced in Japan. The word "hentai" can closely be matched to the word "lewd" in the English language. If you wish to correctly label Japanese pornography, you would use the word "Poruno" or "ポルノ", which roughly translates to Pornography. Porn in a manga would thus be called "Manga no poruno".
