when is the best time to use vulgarities?

well let me show you a few examples in which it's the right time to say some nasty stuff.

"What the fuck was that?" - Mayor Of Hiroshima, 1945

"Where did all those fucking Indians come from?" - Custer, 1877

"Any fucking idiot could understand that." - Einstein, 1938

"It does so fucking look like her!" - Pablo Picasso, 1926

"How the fuck did you work that out?" - Pythagoras, 126 BC

"You want WHAT on the fucking ceiling?" - Michelangelo, 1566

"Where the fuck are we?" - Amelia Earhart, 1937

"Scattered fucking showers, my ass!" - Noah, 4314 BC

"Aw c'mon. Who the fuck is going to find out?" - Bill Clinton, 1999

"He fucking tried to kill my daddy!" - George W. Bush, 2002

"Where are the fucking WMDs?!" - UN, 2003

"Oh, fuck." - Saddam Hussein, 2003

"Geez, I didn't think they'd get this fucking mad." - Osama bin Laden, 2001

yes, indeed 'fuck' is about the most versatile word in the English language. it is by its own worth a noun, pronoun, verb, adverb, adjective, clause, subject etc. it survives in any context, with or without oxygen.

right. although one of the favourites in my arsenal of gentle expletives, "fuck" still does not top "cheebye" (or "chibai", "cibai"... as socially inferior classes spell it) as the most special word in my special box of vocabs. there is a unique aura that surrounds this word. it just sounds powerful when you say it. CHEEBYE. a slow ch- intonation followed by a very abrupt and 'fuck-you-in-the-face' BYE resonance. the fact that it is not as adulterated as the word 'fuck' has only increased the emotional and aural value of 'cheebye'. the word should therefore be used sparingly and not so fucking freely as the average vulgarity in order to preserve its value.

when you are running in the house and accidentally ram a toe into the teak furniture, thats a greenlight. CHEEEEEBYE.

or if you close a door and dimwittedly leave a pinky in the hinges. FUCK LA CHEEEBYE.
length of the CHEEEEEE reverbation can be modulated according to the level of fucked-up'ness of the situation.

remember kids, dont overuse it, or we will end up with another very useful but meaningless word such as 'fuck'. the cheebye is precious. treasure it. caress it. dream of it. worship the cheebye, but dont overexert it.

and selamat hari raya to our muslim friends. yay. ya and cheers to our indian buddies too.
