Entrance applause has been a staple of multi-camera sitcoms for decades, especially in American comedies filmed before a live studio audience. When a familiar face or special guest appeared, the audience would cheer on cue and the actor would pause before speaking. Online, that reaction was isolated as a reusable meme sound, popular in Portuguese-language edits under the phrase artista em sitcom. Creators now drop it over any entrance, from celebrities to classmates, to borrow the feeling of a beloved guest star arriving on set.
