Another word for a rusty trombone: when a girl gives a man a rim job and reaches around to jag him off simultaneously. Very often when the woman pulls her lips off the ass, a rusty colored residue is left behind. Since Louis Armstrong was rust-colored and played a wind instrument, and a girl needs to be "arm-strong", this term is extra appropriate.
