Cliché

A cliché or cliche is an expression, idea, or element of an artistic work which has become overused to the point of losing its original meaning or effect, even to the point of being trite or irritating, especially when at some earlier time it was considered meaningful or novel.

Quotes

 * Everywhere, unthinking mobs of "independent thinkers" wield tired clichés like cudgels, pummeling those who dare question “enlightened” dogma. If “violence never solved anything,” cops wouldn’t have guns and slaves may never have been freed. If it’s better that 10 guilty men go free to spare one innocent, why not free 100 or 1,000,000? Clichés begin arguments, they don’t settle them.
 * Jonah Goldberg, "#22", The Way I See It
