The “Late Show” host lightheartedly claimed he was “pre-enraged” with the institution’s editors for selecting “post-truth” as 2016’s most important word.

“First of all, post-truth is not a word of the year, it’s the two words of the year, hyphens are for the weak,” the comedian said.

His second and more major concern, however, was that “post-truth” was “clearly a rip-off of my 2006 word of the year ‘truthiness.’”

Colbert went on to compare his decade-old definition of “truthiness” and the Oxford Dictionaries’ interpretation of “post-truth.”

And there are some very definite similarities in the words that can both be used to partially explain why the United Kingdom voted to leave the European Union and what led Donald Trump to win the U.S. presidential election.

“I personally believe I’m getting ripped off,” Colbert later quipped.
