These video clip represent the accident in september 2011[2011.08.27 but they descript as september on second video]
original video - http://www.youtube.com/watch?v=Nyw1aCbgm8g
aftermath(some bus driver reject black passenger) & parody about this case by another foreigner who stay at southkorea - http://www.youtube.com/watch?v=a-21pZfzeGI
One of Korean word which one mean 'you' or 'yours' exactly sound like 'ni' 'ner' 'nae' 'nega' and 'niga'(Last word occur situation like this on the youtube video, link1)
'catch' 'get' pronounce 'jap da' 'jap a' 'ut da' etc...
These both word exactly same pronounce as 'bad word'
This is the why I avoid foreign user when already group with korean user.
The exception is who can speak korean fluently like 'blackruby' - one of gods and generals member.
At least he know what we talk and low chance of misunderstood...
* seriously who report 'kansonae' and let him get 3days ban? he didn't speak any racism or aggressive word.
