Jimmy Kimmel said President Donald Trump has changed his tariff policy so often that the process has been given a mocking new nickname: TACO.

That’s short for “Trump Always Chickens Out.”

“You’re not gonna believe this,” Kimmel said. “He doesn’t like the nickname at all.”

TACO refers to how Trump frequently announces a new tariff, causing markets to crash, then backs off, causing them to rise again. Some investors have used it to make cash in a time of economic uncertainty.

Kimmel said Trump flipped out at a reporter who asked him about the name, calling it “a nasty question.”
