Prince Harry slipped in an Americanism during a web chat, just seven months after moving to the US.
The Duke of Sussex used the phrase “pop the hood” during a Time100 Talks roundtable with digital experts – wording far removed from the Queen’s English he was raised on.
He was describing how he had gathered together social media experts to help find solutions for improving online communities and used an analogy about a car breaking down.
Wearing a blue suit and white shirt, without a tie, the 36-year-old former senior royal said: “The media role is vital in everything going on.
“Always has been, always will be.
“There is a huge amount of trust we put into media.”
The duke then moved into the car metaphor to describe how he and wife Meghan Markle had gathered social media experts, including Reddit co-founder Alexis Ohanian and Tristan Harris of Netflix hit Social Dilemma.
“When driving a car and all the warning lights are going off, there is smoke pouring out of the hood.
“You are not going to keep on driving.
“You pull over.
“In the olden days, you’d probably pop the hood up, have a look under it and maybe fix it.
“But now, every single one of these new cars has a shield over top so you can’t fix it – you’ve got to call experts in.”
He added: “The online world is affecting the world.
“It is not restricted to certain platforms of social media groups. This is a global crisis.
“A global crisis of hate. A global crisis of disinformation and a global health crisis.
“These people we speak to there is no one else better to explain it.”
California-born Meghan, meanwhile, introduced the web chat and sat alongside Harry, herself going on to reveal she no longer uses social media due to the impact of “damaging” trolls.
The ex-Hollywood actress picked up plenty of British phrases from her two years living in the UK.
In August, US pals told how the duchess, 39, has often slipped into an English accent since returning to the States.
An insider told The Sun : “Meghan was the all-American girl before she met Harry, but since living in the UK she’s adopted certain phrases.
“Her staff think it’s amusing to listen to an American celebrity using Britishisms. She’s often heard saying, ‘Oh dahling,’ to people at home.
“They do have a giggle about it and sometimes they do impressions of her but only in a light-hearted way. It’s funny to them.”
