Fangirl screams have become a shorthand online for intense excitement, borrowed from the sound of live television studio audiences, concert crowds and red-carpet events where fans react loudly to seeing a favourite performer. Editors reuse this kind of generic crowd reaction because it is instantly recognisable without needing a specific show or celebrity attached to it. On short-form video and in memes, it signals adoration, shock or playful exaggeration, especially when the on-screen reaction is deliberately smaller than the noise suggests, which is why the clip keeps circulating as a reaction sound.
