Swear words are part of every language.  And people use them all the time. 

We all use swear words from time to time.  Either by our internal or external voice (most of us use our external voice with them).  But the people at Bad Science have an article on how the words are ranked from “worst” to “least worst”.  Damn some of my favorite words at the top of the list (not the number 1 entry!).

This image (is the listing) is from another site (the article), I just linked to it.
