Racist or something?

This is the second time in a month that something I see/read about is carried on through out several different mediums.  The last time this happened it was: kancho.  I had seen it done on a Korean drama I was watching.  I also saw a blog post about it.  But before that even happened I had mentioned kancho to a fellow blogger.  What was up with so much kancho suddenly?!  I dunno....  But I digress.
