Boo Hoo : Thats how the Japanese Boo

20 million Symbian smartphones shipped in Japan.
Thats good enough reason for the Japanese to BooHoo the westerns.
You even get to see the video of the westerns getting booed by them.

FYI:
A Boo is a type of ghost that appears in some of Nintendo's Mario video games. When Mario (or Luigi) looks toward this creature, it blushes, covers its face, and stops moving. When Mario turns away, the Boo becomes vicious and chases him. A larger boss version exists, known as "The Big Boo." Other types include "Fishin' Boo", who floats overhead dangling a lethal blue flame.
