Search traffic on "apoplectic" and "complexifier" spiked Thursday after Amazon founder Jeff Bezos used them in a blog post accusing National Enquirer's parent of "extortion and blackmail."

Bezos used the words in a Medium.com blog post directed to American Media Inc. (AMI) CEO David Pecker, leaving many to take to the web to look up their meanings.

And some question whether complexifier is even a word.

Bezos, who owns The Washington Post and is also the world's richest person, used the word "complexifier" twice in the lengthy post related to his ownership of the newspaper.

Vocabulary.com defines complexifier as a noun meaning "someone makes things complex."

Merriam-Webster Dictionary does not have a definition or an entry for complexifier, although it does define "complexify" as "to make complex." The online dictionary did issue a Trend Watch report on apoplectic Thursday night. Searches for apoplectic were up 1,300 percent, Merriam-Webster reported.

In the blog, Bezos wrote: "Several days ago, an AMI leader advised us that Mr. Pecker is “apoplectic” about our investigation. For reasons still to be better understood, the Saudi angle seems to hit a particularly sensitive nerve."

According to the Trend Watch, apoplectic means "of, relating to, or causing apoplexy or stroke" and "extremely enraged." The report said searches for apoplectic occasionally spike.

Bezos used the word "apoplexy" – defined by Merriam-Webster as "a state of intense and almost uncontrollable anger" – in the next paragraph.

Dictionary.com also reported apoplectic was trending.
