Sometimes you need to get the point across in the universal currency of strong language. Swearing.

I don't often swear. Either online or in person. IMHO it cheapens the language. When I swear most people around me realize it is not done casually. That said it has a place. To break people out of their complacency and fog.

That and knowing how to do it, do it well, and in several languages is a moderately useful skill. And knowledge is fun.
