The young skateboarders of the Tokyo Olympics are definitely having a sick summer, just not the kind of “sick” we’re used to in a pandemic.

Momiji Nishiya and Yuto Horigome aren’t the only ones in the spotlight, though. Ryo Sejiri, a 24-year-old professional skateboarder who was tapped as a commentator for NHK’s skateboarding coverage, has had some Japanese viewers checking their dictionaries to get to the bottom of what he’s saying.

The Japanese media has even taken to referring to the skater’s style of laid-back commentary as "瀬尻節" (Sejiri-bushi, the song of Sejiri).
