How do you spell "XXX?"

or

How to say "H" in Japanese...

Okay, gaijin ...
The nihongo word for "pervert" or "perverted" is "Hentai."

So...
The letter used for sex in Japan is H, not X. Get it?

Now...
The letter H is not pronounced "AYch" in Japan like it is in the U.S.
It's pronounced "EC-chi."

Aren't you glad you came here to learn this?

Bye.
