Snark. If I was the eighth dwarf, I'd be Snarky. Shocking, I know.
In the old days, it was called sarcasm. Now it's called snark. It's probably not the most effective form of communication, but it sure is one that I enjoy.
A friend of mine once said to me "You don't suffer fools gladly" and I think that's pretty accurate. Generally, I'm patient with those who deserve and need my patience but for people who are arrogant, self-centered and oh-so-self-important, Snark is my weapon of choice.
