Kim, the word you want is "Dudelsack". What you have given us sounds perilously close to either "Dudelsackkiffer", which might mean a pot smoking bagpiper - I guess there must be some... The other thing it sounds perilously close to is "Dudelsackficker", which would mean a piper who.. erm...does something one does not usually do with a set of bagpipes! (You pronounce the correct German word "doodlezack").
