Online, this clip is shared as a waiting sound linked to Indonesian quiz-style videos, where the phrase tunggu soal means waiting for the next question and deg deg describes a nervous, thumping heartbeat. That combination explains its role: it fills the awkward gap between a question being set and an answer being given, keeping the audience in suspense instead of letting the moment go flat. Because the sound is short, instantly recognisable as tension, and easy to drop over edits, quiz creators, reaction channels, and challenge makers keep reusing it whenever a result is about to be decided.
