Those "dirty" words

There's great little piece at the Philadelphia Enquirer on the use of dirty words and the wild variations from culture to culture. Its seems, universally that people like to use sexual words to express their anger or agression towards another. It seems that most taboo expression is rooted in spiritual superstition and elaborate rules about mixing sex and speech. For Americans, FUCK is still the supreme being as if we needed reminding. What I didn't know is that word is 1000 years old and pretty much the king of the hill for the last 400 years. It has nothing to do with "for unlawful carnal knowledge"! The sad part is, that experts are concerned that its over usage may deem it mute. Wouldn't that be horrible!
