The sound is associated with America's Got Talent and the show's Golden Buzzer format, where a judge sends an act straight through in a highly emotional moment.

It keeps showing up in short-form edits, reaction clips and meme videos because viewers immediately understand the stakes and the payoff, even when the moment being celebrated is completely trivial.
