Biden aides struggle to explain bizarre phrasings like 'God save the Queen'

Even President Joe Biden's staff members have no idea what he means when he says things like, 'God save the Queen' - which is how he ended a gun safety address on Friday. 

On Sunday, Axios headlined a story 'Biden's weird words,' which detailed several Bidenisms that left aides scratching their heads. 

Biden's deputy press secretary Olivia Dalton initially said the 'God save the Queen' reference was made because the president 'was commenting to someone in the crowd.'

Later, the White House didn't respond when Axios' requested an interpretation from the press office. 

Several current and former aides said they didn't know what the phrase meant.

On Friday, President Joe Biden concluded a speech in Connecticut by saying 'God save the Queen' and telling the audience not to turn him into a 'dog-faced lying pony soldier' 

Others gave Axios conflicting explanations. 

Another notable time Biden used the phrase - as vice president in January 2017 when he was certifying President Donald Trump's 2016 election win - doesn't make it any more understandable. 

As an Irish-American, there's some speculation that the president uses it sarcastically. 

But Friday's utterance comes nearly a year after the death of the long-reigning British monarch. 

And Biden attended the funeral of Queen Elizabeth II. 

During his Friday speech in Connecticut, Biden not only concluded his remarks by saying 'God save the Queen,' but he also told the crowd not to turn him into a 'dog-faced lying pony soldier,' a phrase he claimed came from a John Wayne film. 

President Joe Biden is captured speaking Monday from a nature reserve in Palo Alto. His use of Bidenisms prompted Axios to write an entire story Sunday about 'Biden's weird words' 

He had previously deployed a similar line at a 2020 campaign event in New Hampshire - a bizarre moment that went viral. 

A number of film buffs have tried to track down the movie Biden was referencing, but have come up short. 

The film critic Farran Smith Nehme suggested at the time that Biden might be thinking of the 1952 film Pony Soldier, but Wayne does not appear in that movie. 

Another head-scratcher of a phrase came during this year's State of the Union, when Biden told Republicans in Congress, 'Lots of luck in your senior year.'

While the phrase seemed to be Biden sarcastically wishing House Republicans the best of luck, the White House wouldn't say - even when The New York Times wrote an entire story about the president using it.
