Oh japan and your nicknames xD Saw this on gaf
The Xbox consoles are not popular in Japan. That doesn't mean those game machines lack hardcore fans. They certainly exist in the region. And online in Japan, there's a disparaging nickname for them: "gropers".
The Japanese word is "chikan" (痴漢), which translates as "groper" or "molester". "Chikan" is certainly not something anyone wants to be called, but online in Japan, it's how hardcore gamers mock Xbox fans.
It's also a word that you can see on Japanese public transportation, either on notices or via PA announcements that point out the obvious: "Chikan wa hanzai desu" (痴漢は犯罪です) or "Groping is a crime". Some in Japan dislike these warnings as they imply that everyone could be compelled to touch fellow passengers on the train, which is simply not true. Regardless, groping has been enough of a problem to warrant said announcements as well as women's only carriages.
The groper nickname originated back when the first Xbox launched in Japan in 2002. According to Nico Nico, the media interviewed people lined up at Akihabara retailer Messe Sanoh for the Microsoft console. In a separate line, there was a customer waiting to buy an adult computer game called Ryoujoku Chikan Jigoku who also said he planned to buy the Xbox. Thus, "chikan" apparently came into use online to describe Xbox gamers. Games like Dead or Alive, Dream Club, or Japan-only visual novels with young female characters only reinforced the "chikan" nickname and made the Xbox seem like a pervy console.
As opposed to "chikan", the less offensive and unsettling way to refer to Xbox fans in Japan is simply "MS shinja" (MS信者) or "Xbox shinja" (Xbox信者), with "shinja" (信者) meaning "believer" or "follower". Basically, you're calling someone a zealot.
While online "chikan" is still the standby to mock Xbox fans, Microsoft's upcoming console, the Xbox One, already has a new nickname in Japan. While it's called "Xbone" in the West, it's being called "divorced" in Japan.
