-interesting- I heard recently that Tokyo, following Meiji, actually imported choice parts of the kyoto area dialect to replace the rougher sounding native edo dialect. The one example i have is 行くべい being replaced by the now standard 行きましょう (apparently, that style of speech is or was associated with Kyoto, and therefore, kansai).
so, if you mean vulgar in the sense of common place, then kansai is not the place to generalize.
mecha kansai pride!

I had never heard that before. Interesting stuff. Sometimes people forget that Kyoto was the capital before Tokyo.

i've read that keigo comes from kansai but i'd never heard of your example MrDrEsq so if that is true it is very interesting.

don't know a whole lot about historical japanese, don't know anything for that matter, but there be whispers around the department about keigo being court speech- some keigo even coming directly from words that were used only to refer to and talk to the emperor. I also know that some funky kind of slang came out of the court too. apparently it was uncouth to talk about food directly so the women came up with slang. examples being agari for tea, murasaki for shoyu, gari for ginger. anyway, flash forward a couple hundred years and the slang is still beign used. by old women, sometimes, but predominantly in sushi bars as, i guess, sushiben
