The title is Dutch for countdown from ten, and the artist credit points to a kermis, the travelling fair common in the Netherlands and Belgium. Sounds like this are staples at fairgrounds, school events and sports days, where an announcer counts the crowd down together before an attraction starts or a result is revealed. Online, creators reuse that familiar ritual for edits and livestreams, because everyone instantly understands the format and joins the anticipation without any explanation needed, whatever language they normally speak during the clip itself.
