Put it at the very beginning of the edit, then follow it straight away with the Run Vine Sound Effect as the group takes off, and save the Yaaaay Cheer Sound for the moment the plan actually works.
Über diesen Sound
This is a loud Russian voice clip lasting just under six seconds, opening with a casual greeting to the group before erupting into an energetic shout to get moving. It feels hyped, impatient and mischievous, like friends agreeing to do something reckless together. The phrase is Russian internet slang for rallying everyone onward, with a blunt ending that adds its pushy, no-turning-back edge.
