Pope Leo gave the viral "6-7" gesture his blessing after a crowd of young Catholics taught him the meme during a visit to Rome.
The moment happened when about 1,000 young Catholics from the Archdiocese of Genoa traveled to Rome as part of their preparation for the sacrament of confirmation.
Influencer Don Roberto Fiscer later uploaded the clip, which has now been viewed more than 18 million times since Saturday (May 16).
“Since the Pope is one of us, and we greet each other like this, he must learn this greeting too, especially because kids all over the world greet each other like this,” Fiscer told CNN. “So the kids made us feel close to them, and we made him feel that we consider him one of us.”
The "6-7" meme originated from Philadelphia rapper Skrilla and his song “Doot Doot,” which became widely used in viral videos online.
Skrilla has said "6-7" can mean different things depending on the person using it.
“For me, it's just 'negative to positive," he explained. "It helped me turn from a negative person to a positive person.”
Dictionary.com, which named “6-7” its Word of the Year in October 2025, has suggested the phrase can also mean "so-so" or "maybe this, maybe that," while many younger users have adopted it as a catchall response that leaves older generations confused.
