A smoking device made from a trombone, generally used to smoke cannabis. The mouthpiece is used as the bowl and the spit valve is the carb. Water is not actually used, however "trombong" sounded more catchy then "trompipe".
"Dude, after you finish that B flat scale, take another hit from the trombong. Wurd."
