This is the name given to a silly sound effect that I made up one morning on the bus to school, and me and my friend Angelo Martinez would recite it over and over again during a dull moment. There is a background to this sound effect, and it goes as follows - There is a man with a whip chasing a another man around a ring. Next to the ring is a guitarist, who plays that "dun de le dun de de de dun" sterotypical spanish tune constantly. The two men are quite close to each other as they run, and at the end of each playing of the song the man with the whip cracks his whip on the man in front's arse, causing him to yelp with pain. So it would go - "Dun de lun dun de de de dun PSCHH ha HOO!" You really have to hear it to understand it. When we got tired of doing it, we would finish by slightly altering the last "ha hoo" so that the "hoo" would be long and drawn out and falling in pitch, as if the man who was being chased had fallen down a chasm or fallen off a cliff or something.
