Duke fans, you might want to sit down for this one—Cooper Flagg has a new nickname, and it's turning heads.

The rising NBA star, who just clinched the Rookie of the Year Award, took a moment during Wednesday's pre-trophy press conference to address a question that caught him off guard. When reporters asked if he'd heard the moniker "Cooper Swag," the former Blue Devil looked genuinely puzzled at first.

"I've never heard that, but I think it's cool," Flagg said with a shrug, eventually giving it his seal of approval.

It's just the latest addition to a growing list of nicknames for the 19-year-old phenom. Fans have already embraced "The Maine Event," a nod to his home state roots, and "King Coopa," a playful reference to Nintendo's iconic villain Bowser. Each one captures a different side of Flagg's game—from his small-town grit to his dominant presence on the court.

No matter which nickname sticks, one thing's for sure: the former Duke forward is poised to take another massive leap in the 2026-27 season, and his growing fanbase will be cheering him on every step of the way.
