“at the end of the day”
“At the end of the day”
That one annoys me, but it’s a pretty descriptive aphorism.
Here are some that annoy mean because the original meaning is (mostly) lost: Mixed bag, cakewalk, decimated.
One of the most deeply ironic aspects of American English is that "the truth of the matter is" has NEVER been followed by a statement of truth.
If you hear "the truth of the matter is," prepare for a lie, usually one that is astonishingly brash and shameless.
