Maybe, influenced, would be a better word.

An Austrian young man told me 10 years ago when I studied abroad there that "Arsch" and "Leck mir am Arsch" were among the dirtiest swear words.

Die schlimsten Schimpfwoerter

Then again, we're not sure exactly HOW vulgar this sort of thing was at the time it was written. It certainly was considered vulgar, but it may have been thought of as no more "shocking" than something Bart Simpson would say would sound to our ears. I say this because a good deal of the "naughtiness" of the 18th Century was suppressed in 19th Century histories (which treated Mozart as a well-behaved musical genius and made little or no mention of his bizarre behavior), so we have a rather "sanitized" view of the past. Also, the song "Yankee Doodle," well-known to all American schoolchildren, is really a very raunchy song that basically says, "The soldiers of the Continental Army are a bunch of sissies who are so ugly they have to masturbate ("yankee doodle") because the ladies won't go near them. Also, Thomas Jefferson is a dandified fop who thinks his "macaroni" is such a great invention..." The song became popular in the Colonies immediately (despite the fact that it was intended as an insult), and was sung by children after the Revolutionary War was over. My guess is that it was not to be sung in mixed company, and that it was felt there was no harm in young children singing it, because they wouldn't know what the slangs meant. As with many slang terms, these fell into disuse, and it wasn't long before even strait-laced schoolmarms were teaching the song to their pupils, with no idea how raunchy the song was. (If only they knew what it meant!)
