Paul Krugman predicts a 'derp spiral' when Trump realizes he's likely to lose

Nobel Prize-winning New York Times columnist Paul Krugman coined the phrase "derp spiral" on Tuesday in preparation for Donald Trump's behavior once he decides he will likely lose the election in November.

"Aha!" Krugman exclaimed on Twitter. "I think I have the term for what happens to Trump if (when) he finds himself ever more likely to lose: he will go into a derp spiral."

KnowYourMeme defines derp as "an expression associated with stupidity."

While trying to change the subject from his attacks on a Muslim family whose son died fighting for the U.S. Army in Iraq, Trump called Hillary Clinton "the devil" on Monday. And he warned that the election could be "rigged" to prevent him from winning.

On Tuesday, he continued to suggest that Hillary Clinton was the devil at a rally in Virginia, where he also ordered a baby removed from the event and pocketed a Purple Heart from a wounded veteran.

Two recent polls showed Hillary Clinton inching toward double digit leads this week following the party conventions.

Trump is scheduled to appear at two rallies in Florida on Wednesday before traveling to Portland, Maine on Thursday.
