Former Vice President Joe Biden was kidding around during a question-and-answer session with voters in New Hampshire on Sunday and, reaching into his bag of weirdo Uncle Joe phrases, pulled out “lying dog-faced pony soldier.” The audience chuckled along while listening to the man who once faced-off against a razor-wielding gang leader named CornPop.

A young woman asked Biden what he thought his true chances of winning were after his fourth-place showing at the Iowa Caucus. He responded by asking if she had ever been to a caucus, and when she said that she had that’s when he slipped in the oddball diss. He continued on to explain how complex the voting process is in Iowa, and why he feels it isn't relevant.

This is not the first time Biden has used the unusual euphemism. At a 2018 rally for Senator Heidi Heitkamp he quoted his brother’s use of the expression, which he allegedly got from an old John Wayne movie.

V.F. is currently unable to definitively source which John Wayne movie this is from, but considering everyone thought CornPop was made up we’re gonna give Joe the benefit of the doubt on this one.

However, classic film critic Farran Smith Nehme, whose marvelous commentary about Bette Davis can currently be seen on Criterion Channel, weighed in with her theory.
