The "F" word is actually an acronym from the old days of a young country, not really sure if it was even ours. In the constabulary's offices were several sets of penalties and fines dealing with whatever was titled at the top of the pages. For Unlawful Carnal Knowledge was the title of one of these pages. You can see how it was shortened by acronym and eventually became a "dirty word" especially when prostitution is generally known as the world's oldest profession. I'm guessing it was in Puritan times.
I'm tired of "It is what it is" and "Whatever." Being called Dude by somebody even older than I pisses me off and makes me want to slap them silly.
And even though it's not words, I want to yank up kids pants today until I pull them off the ground.
