A few phrases, like "that one" and "lipstick on a pig," achieved instant notoriety in the current election season after one of the candidates said them once and everybody pounced. But others seem to come up again and again just because somebody can't stop himself or herself or themselves.

Here's a short list of words and phrases of this latter kind. I, for one, would be grateful not to hear or read any of these again until 2009, or 2012 -- or ever:  

a heartbeat away
hockey mom
my friends
Wall Street vs. Main Street
what he doesn't understand
the most important election in history
