This four-second brass sting slides downward in a slow wah-wah pattern, sounding like a small band giving up mid-note. It feels comic and deflating, turning a mistake into a shared laugh instead of a serious moment. The sagging notes make embarrassment feel light, playful and instantly recognisable as a fail.
