WOMEN AS EXPLAINED BY ENGINEERS................!!

Most interesting and colorful word in the English language

Perhaps one of the most interesting and colorful words in the English language
today is the word "fuck". It is the magical word which, just by its sound can
describe pain, pleasure, love, and hate.

In language, "fuck" falls into many grammatical catagories. It can beused 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), and adverb (Mary is fucking interested in John), or as
a noun (Mary is a terrific fuck). It can also be used as 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
versitility of the word "fuck".

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

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

It can be an anatomical description............."He's a fucking asshole."
It can be used to tell time....................."Its five fucking thirty."
It can be used in business.............."How did I wind up with this fucking
job?"
It can be maternal......................"MOTHERFUCKER!"
It can be political....................."Fuck Newt Gingrich!"

Lastly, it has 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--

"That's not a real fucking gun."
--John Lennon--

"Where the fuck is all this water coming from?"
--Captian of the Titanic--

"Who the fuck's gonna find out?"
--Richard Nixon--

"Heads are going to fucking roll!"
--Anne Boleyn--

"Any fucking idiot could understand that."
--Albert Einstein--

"It does so fucking look like her!"
--Picasso--

"How the fuck did I work that out?"
--Pythagoras--

"You want what on the fucking ceiling?"
--Michaelangelo--

"Fuck a duck."
--Walt Disney--

"What do you mean why...becuase its fucking there!"
--Edmund Hilary--

"Don't fucking light that..."
--Joan of Arc--

"Scattered fucking showers my ass."
--Noah--

"I need this parade like I need a fucking hole in my head."
--John F. Kennedy--

"Houston...we've got a big fucking problem..."
--Crew of Appollo 13-
