The Washington Post (October 30 issue) carried an article under the headline, “Will Trump be ‘Brexit times five’? He may need to be if he wants to win.” which is followed by the following passage:
“The Republican nominee has repeatedly fed that belief, calling himself “Mr. Brexit,” predicting “Brexit times five” and vowing Tuesday that “there’s going to be a lot of Brexit happening in about two weeks. A lot of Brexit.”
I surmise Mr. Trump is predicting his big victory in the Presidential election in the scale of five times as much large as Brexisists’ victory, which few anticipated to happen. Am I right?
Is “X times five” a common idiom to describe a big number or large scale gap in comparison with something (X)? Why should it be five, not three, seven, ten, hundred, or any other number?
