Place it at the start of a reveal, as the person or product enters, then follow the entrance with a shocked sound for the onlookers' reaction and a goofy yell when the moment turns playful.
About this sound
A ring announcer loudly calls out John Cena as his entrance theme starts and a crowd roars, in a clip lasting just over twelve seconds. It feels sudden, funny and overblown, turning an ordinary arrival into a mock-heroic moment. The moment comes from Cena's televised WWE entrance, which editors later cut into unrelated videos as a joke about an unexpected arrival.
