An improved rusty trombone. It is a maneuver similar to a 69, but instead one participant performs a rusty trombone while receiving oral gratification. The name is derived from how one partner is "wrapped" around the other being played like a sousaphone. Preferably one of the performers is standing.
Steve slipped a disk the other day when he received a shiny sousaphone from Shannon the other night.
