Cheehoo comes from Samoan and wider Polynesian street culture, where it is shouted as an exclamation of excitement, pride and encouragement. The call is closely associated with Samoan performers and athletes, and it reached a global audience through social media clips, rugby celebrations and figures such as Dwayne Johnson, as well as Maui in Disney's Moana. Online, creators shortened it to a standalone reaction sound that can be dropped onto any triumphant moment. Its appeal has lasted because one word carries both a cultural cheer and an instantly readable burst of joy.
