Alright, here comes the japanese lesson from anime. As you know, kansai dialect origins from Osaka. And their language sounds similar to our chinese dialect.
Meaning can be deceiving. If you happen to bump into an "Osaka-jin", dun be agitated by their way of apologizing. "Kanina" is their way of apologizing. What? You don't believe me? Then I have 2 evidence from here. One is from School Rumble Season 2, and another is Mai Hime.
Next time if you accidentally did something wrong to you or anyone close to you, just one "kanina" will do the job ^_^ For example, if someone kills you/you killed someone in Dota, just "kanina" him will do... It's friendly game anyway XD
