The clip is a single drawn-out vocal shout of 'vaaaai', lasting about 1.4 seconds, with the word stretched until it sounds like a playful nudge rather than a command. It feels light, cheeky and encouraging, the kind of sound that turns a simple go-ahead into a joke. It lands best as a quick burst of energy, not a serious instruction.
