Trying to appear reasonably intelligent and well-spoken? Omit these three trite phrases from your limited repertoire:
“It’s to die for.” There are things worth dying for but chocolate cake is not one of them.
“It is what it is.” Is it also not what it’s not? Just stupid.
“It costs an arm and a leg.” Only appropriate when negotiating price with Jeffery Dahmer. Just say “it’s expensive.”
