Actually, I go every year to the American Dialect Society's annual meeting and vote in the famous "Word of the Year" event. So I hear every year many of the witty, funny new words that are around. I was so pissed last year that "freedom fries" beat "Bennifer" as "Most Unnecessary". What could be a more useless word than "Bennifer", while I myself used "freedom fries" when I was in France for humor purposes??
During the days of the dot-com bust in 2000, here are some words I liked:
dot-snot: A twentysomething dot-com millionaire exec who blows his money on anything real fast.
dot-bomb: A failed dot-com.
starter castle: A dot-commers first home.
Here's a full list with voting results:
