Ah, internationalization.

Our student council at Jr High. I direct your attention to the upper left hand corner, where one of the student council members is flipping the bird.

This pic is posted up in the school for all to see. It's funny, because it's even odds whether the kid even knows what it means, other than something he saw in a western movie or TV show. And the same reason it's posted up in the school. The meaning isn't really widely known or understood.

Though I did have a kid blurt out an appropriate "Fuck!" in class the other day [in place of "yabai"] when he got his test back. Of course, after I made a stern face at him [while barely not laughing myself to death] he had to ask one of the other kids what the meaning of the word was.
