(The American public may be unfamiliar with the word, but Biden himself isn't. As The Fix's Jaime Fuller reported several "malarkeys" ago, the vice president "has said the word 'malarkey' more times in public than any human (or at least, member of Congress) since the 19th century, as backed up by data provided by the Sunlight Foundation.")
Of course, since Merriam-Webster won't give anyone hard search numbers, we don't even know much about the actual size of that spike: The company doesn't say precisely how many people looked up the word "malarkey" in the 24 hours before Biden's speech or the 24 hours after — so we could be talking about a jump from one search to 175.
But this much we do know. The words "malarkey," "hypocrisy," "treason" and "demagogue" are all on people's minds leading into Hillary Clinton's convention speech Thursday night.
How do we know that?
The first happened after billionaire businessman, independent and former New York City mayor Michael Bloomberg made a speech at the Democratic convention endorsing Clinton. During his address, Bloomberg used the word "hypocrisy" in describing Trump.
Truth be told, the richest thing about Donald Trump is his hypocrisy. He wants you to believe that we can solve our biggest problems by deporting Mexicans and shutting out Muslims. He wants you to believe that erecting trade barriers will bring back good jobs. He's wrong on both counts.
"Treason" got a boost after Trump himself called on Russia to launch a hacking operation to find Clinton's deleted emails. Trump, his campaign and his surrogates spent much of the day Thursday arguing that the statement was a sarcastic joke.
Also on Thursday, the word "demagogue," a term that's been used throughout the 2016 election in reference to Trump, became the most searched word of the day.
By the way, late Thursday, "malarkey," like Biden, held the No. 2 slot.
