Stephen Colbert on Tuesday cooked up a definition for a new non-word Donald Trump used as the former president attacked immigrants at a rally over the weekend.

“They’re just getting acclamented,” Trump said. “You know what that means.”

“No,” Colbert fired back. “No, I don’t know what that means ― ’cuz that’s not a word!”

Colbert went back to the video to hear Trump’s attempt to define it.

“Acclamented. They’re getting used to a society that really goes too far,” Trump explained.

“Oh, acclamented. I understand,” Colbert said. “I think that’s when you get acclimated to Trump being demented. It’s acclamented.”
