"Swearing is but a crutch upon which uneducated people lean to express themselves." Roc's Rule #67
One of my pet peeves, as well.
There's nothing wrong with a little profanity every now and then. Linguistic salt & pepper, if you will.
But if you are using various derivations of "F" as noun, verb, adverb, adjective and imperative, all in the same sentence, then get a thesaurus and have some alone time.
