This sound is best understood as a meme edit format rather than a clearly documented quote or soundtrack clip. Online creators use the sneeze-to-boom timing as a quick bait-and-switch gag: the setup sounds normal, then the impact lands far bigger than expected. It fits the same exaggerated reaction style as goofy ahh sounds and a classic bruh stinger, which helps explain why it keeps showing up in short videos, compilations and ironic meme edits.
