A ten-second stretch of rapid nonsense speech that loops through bla bla bla, ble ble ble and bla bla blu in a flat, mocking patter. It feels dismissive and silly, like tuning out someone who keeps talking without actually saying anything, and turns that glazed-over reaction into a joke you can hear.
