While wiping one's ass after dropping a deuce, an individual releases a fart, of which the sound pitch changes because of the location of the hand and toilet paper near the anal region.
Similar to when a trumpet player would apply a "plunger" during play to change the sound of his instrument. Wynton Marsalis is considered one of the best Trumpet players of our time, hence the name "The Wynton Marsalis".
