A brief handshake between Donald Trump and Emmanuel Macron has become the latest viral political moment — and according to a professional lip reader, the encounter may have included a five-word “threat” that left the French president visibly tense.

The incident took place last week at a global summit in Egypt, where world leaders gathered to discuss the Middle East peace deal following the ceasefire in Gaza. Cameras captured what initially appeared to be a routine greeting between Trump and Macron — but the handshake quickly turned into a 26-second power struggle.

Instead of a simple clasp, both men tightened their grips, pulling each other back and forth in what many described as a display of dominance. Photographs of the moment went viral, showing Trump leaning in close while Macron maintained a strained smile.

Now, according to professional lip reader Nicola Hickling, there was much more happening beneath the surface. In an analysis shared by The Mirror US, Hickling claimed Trump’s lips appeared to form the words, “You’ll see what happens next.”

The alleged five-word phrase has been described as both a warning and a challenge, depending on interpretation. Hickling noted that Macron’s expression changed immediately after the line, shifting from a diplomatic smile to a more guarded look.

“Trump’s posture and tone suggested he wasn’t joking,” Hickling said. “It wasn’t a friendly exchange — it looked like a private message disguised as a handshake.”

The meeting between the two leaders came just weeks after tensions rose over Macron’s public recognition of a Palestinian state, a move Trump had called “a disgraceful endorsement of terror.” That history added even more fuel to the speculation surrounding the handshake.

Footage shows Trump saying something quietly as he leans in, while Macron replies briefly before the former president gives a slight smirk and steps back. Body language experts have since analyzed the clip frame by frame, calling it “one of the most intense greetings between allies in modern diplomatic history.”

According to Hickling, Macron’s short reply appeared to be, “That’s not how this works.” The lip reader suggested this could indicate the French leader was attempting to defuse what he perceived as an intimidation tactic.

Social media quickly lit up with theories. Some users joked that the scene looked like “a WWE staredown,” while others called it “the world’s most awkward slow dance.” But many were genuinely curious whether Trump’s alleged phrase had a deeper diplomatic meaning.

“Every handshake is a message in geopolitics,” said Dr. Elaine Parker, a political communication expert at King’s College London. “When two strong personalities like Trump and Macron meet, even body language becomes negotiation. A five-word phrase at the wrong moment can send ripples through global relations.”

Neither the Élysée Palace nor Trump’s office has commented on the lip reading claims, though Trump later dismissed questions from reporters, saying, “We had a great meeting — strong leaders, great respect.”

Macron, for his part, offered a more diplomatic response during a press conference afterward: “We have differences, but we also have responsibilities. What matters most is results, not gestures.”

Observers, however, couldn’t help but notice the tension in his tone. “It was one of those rare moments when Macron looked genuinely rattled,” one European correspondent told Le Monde. “He’s usually composed, but there was an edge afterward — like something had shifted.”

This is not the first time a Trump handshake has made headlines. In 2017, the two leaders’ first meeting in Brussels went viral when Macron refused to release Trump’s grip, leaving visible white marks on both men’s hands. Macron later admitted the move was deliberate, saying, “You have to show you won’t make small concessions, even in gestures.”

Whether this latest exchange was playful banter, a veiled threat, or simply another example of Trump’s unconventional diplomacy remains unclear. But one thing is certain — the handshake has reignited debate over Trump’s approach to power and personal relationships on the world stage.

As one commentator summed it up on social media: “Only Trump could turn a handshake into an international incident.”
