Double-faced entendre

A term coined by the band Oliver Tree. It means the exact same thing as two-faced in the context of the song “Life Goes On,” but the words together actually do not make any sense.

“I’m looking for help with this song. I’m trying to describe someone who treats you one way to your face but acts the other way behind your back.”

“You mean “two-faced?””

“No, something more pretentious.”

“That’s the exact phrase you’re looking for.”

“Gosh, he couldn’t just find me new words. What a double-faced entendre.”
