Wasn't it Mark Twain who said, "Slang is language that spits on it's hands, rubs them together, and gets to work."?
Slang has a very useful place in society, often more accurately communicating in one word a person's thoughts than a whole paragraph might. But IMHO slang has it's place and is not appropriate in every place.
I personally use much more care and try to avoid slang when writing on FlyerTalk than I would around friends or in private communications. That's not only because it is a "international" bulletin board where some from other countries might not understand it's use.
The main reason I try to avoid slang here is because of consideration to others. Unlike when talking to friends or individuals, I have no idea who might be reading this forum, and therefore try to be more careful and selective in the way I write so as not to offend some who might find some words objectionable.
I know some will say "Why the h**l should I change the way I write just because of a few who might object to some harmless word or another?" I suggest while you may have every "right" to use some words here, that perhaps you and I should be a bit more considerate that others may find some of those words objectionable. Maybe try to find another way to get the same thoughts and points across.
It's very easy to substitute "ticked off" for "p**sed off." I really feel that LarryU didn't mean to offend anyone. I'm certain that like many, they "write" like they "speak" and that just sounded natural to him. And I also feel that some slang is useful in communicating emotional feelings better than other forms of communication, and would hate to see anyone post what they consider acceptable and/or non-acceptable words. FlyerTalk, as the owners and hosts of this private board are the only ones who are permitted to have a "hit list" of what is inappropriate for their board, IMHO.
