The F word is my favorite word. I learned of it in 7th grade when I went to the public library and took out Lady Chatterley's Lover.
A year or so after, I began reading in newspapers & magazines about the Berkeley Free Speech Movement. I learned that (even though the main object was political speech) you could get arrested for saying that word! You could be fined! I was outraged, outraged I tell you by laws directing which words you're not allowed to say. Censorship, my young teen mind screamed.
Also, the F word is very versatile. It can be a noun, pronoun, adverb, adjective............ It can be used to express varied moods such as frustration, anger, grief, Joy, Love................Anything. It could express anything.
That is why the F word is my favorite word. I use it daily, several times a day as it is often needed to make a good point.
