Extended celebration shouts became a staple of meme editing because one exaggerated reaction can carry a whole joke without any dialogue. This long yeah is shared on soundboards alongside similar cheers like YAAAAAAAAY and other stretched reaction clips that creators swap in for wins, dunks and reveals. Its popularity comes from timing rather than a single source, as editors reuse the same shout across gaming clips, sports edits and short comedy videos. The drawn out delivery still works because viewers instantly read it as pure, unironic joy pushed to a silly extreme.
