tri�fec�ta – n. A system of betting in which the bettor must pick the first three winners in the correct sequence. Also called triple.
I like to use new words which come across the net discussion boards. Trifecta is one of those words. Mostly it comes from betting practices. But now it seems to be used in news stories that come in 3’s. Such as 3 famous people dying of a certain genre during a short period of time. Or it could be 3 plane crashes. 3 of any similar news stories.
George W. Bush used the word in some campaign speeches in 2002.

“You know, I was campaigning in Chicago and somebody asked me, is there ever any time where the budget might have to go into deficit?
I said only if we were
at war
or had a national emergency
or were in recession. (LAUGHTER.)
Little did I realize we’d get the TRIFECTA.”
George Bush – February 27, 2002
