Perhaps one of the most interesting and colourful words in the English
language today is the word "fuck". It is the one magical word which,
just by its sound, can describe pain, pleasure, love, and hate. In
language, "fuck" falls into many grammatical categories. It can be used
as a verb, both transitive (John fucked Mary) and intransitive Mary was
fucked by John). It can be an action verb (John really gives a fuck), a
passive verb (Mary really doesn't give a fuck), an adverb (Mary is
fucking interested in John), or as a noun (Mary is a terrific fuck). It
can also be used as an adjective (Mary is fucking beautiful) or an
interjection (Fuck! I'm late for my date with Mary). It can even be used
as a conjunction (Mary is easy, fuck she's also stupid). As you can see,
there are very few words with the overall versatility of the word "fuck".

Aside from its sexual connotations, this incredible word can be used to
describe many situations:

1. Fraud "I got fucked by the car dealer."
2. Resignation "Oh, fuck it!"
3. Trouble "I guess I'm fucked now."
4. Aggression "FUCK YOU!"
5. Disgust "Fuck me."
6. Confusion "What the fuck.......?"
7. Difficulty "I don't understand this fucking business!"
8. Despair "Fucked again..."
9. Pleasure "I fucking couldn't be happier."
10. Displeasure "What the fuck is going on here?"
11. Lost "Where the fuck are we."
12. Disbelief "UNFUCKINGBELIEVABLE!"
13. Retaliation "Up your fucking ass!"
14. Denial "I didn't fucking do it."
15. Perplexity "I know fuck all about it."
16. Apathy "Who really gives a fuck, anyhow?"
17. Greetings "How the fuck are ya?"
18. Suspicion "Who the fuck are you?"
19. Panic "Let's get the fuck out of here."
20. Directions "Fuck off."
21. Disbelief "How the fuck did you do that?"

It can be used to tell time- "It's five fucking thirty."
It can be used in business- "How did I wind up with this fucking job?"
It can be maternal- "Motherfucker."

It has also been used by many notable people throughout history:

"What the fuck was that?" Mayor of Hiroshima
"Where did all these fucking Indians come from?" General Custer
