Place it at the start of the fast movement, then follow the dash with the Run Vine sound for a second burst of motion, or cut to the Bruh sound when the boast falls apart.
Über diesen Sound
This is a roughly six-second voice clip of one person shouting 'I'm fast as f boiii' with a loud, hyped delivery. It feels funny and cocky, as if a tiny burst of movement deserves a huge announcement. The exaggeration is the joke: a modest dash suddenly sounds like a championship sprint, and that mismatch gives edits an instant lift.
