The f word in English is definitely the best profanity in any language that I'm aware of, and I can curse effectively in more languages than I know many other words in

. Some of the Quebec French profanities are interesting, in that they derive from religious terms and aren't present in other dialects of French.
I do enjoy how this thread has partly become which language has the best profanities

. It's also rather Euro-centric dare I say, but Portuguese hasn't been brought up, which is quite an interesting language in its long development. I find Korean rather interesting myself, in that it looks unapproachable at first, but actually has a relatively simple basis for formation of sounds and hangul symbols, certainly far simpler than that of Japanese or Chinese. Eventually I want to learn Korean. However, many Southeast Asian languages such as Thai or Khmer look incredibly confusing to me in script, I know I'll never have a chance at learning them! It would probably take me 5 years of full out study to even acquire a moderate ability with a language from that area.
