Queen Elizabeth has had a funny reaction to her 69-year-old son calling her “mummy.” Her Majesty, who celebrated her 92nd birthday with a star-studded bash thrown by the BBC on Saturday, was a bit taken aback by Prince Charles’ endearment, inadvertently creating a new meme reaction on social media.

The monarch was surrounded by the evening’s performers — including Australian Kylie Minogue, Sting, Craig David, Luke Evans and Sir Tom Jones — on stage at the Royal Albert Hall. Charles capped off the evening by raising cheers for his mum, and the way he called her a personal name had the crowd laughing.

“Your Majesty, mummy…” Charles said to the delight of the crowd. The Queen had a different reaction altogether, which was even funnier.

Queen Elizabeth appeared to have been spooked by Charles calling her “mummy.” Her eyes got bigger, setting her mouth in downward curve.

“I have a feeling that in 1948 when you were 22, you didn’t somehow expect at your 92nd birthday to find your son in his 70th year just able still to raise a small ‘hip, hip,’” Charles said.

His speech was admittedly short and sweet, but the Internet still couldn’t get enough of the Queen’s reaction to his “mummy. In minutes, the moment was turned into a gif meme.
