Place this clip right after the action peaks in your edit, then follow it with a vine boom sound effect for emphasis before cutting to a spongebob fail sound effect as the aftermath shot.

This is a short voice clip of someone asking 'what is this diddy blud doing' in a confused, mocking tone across about five seconds. It feels playful but judgmental, like instant secondhand embarrassment, which makes the disbelief land immediately. The line circulated as a slang-driven reaction sound through online meme edits rather than from a film or show.
