Generally, bassoon players have very little luck in love and very little action in bed. This word can define a player's personality, or be used as an insult, when said to someone very much the same way Bugs Bunny says "What a maroon!"
Trombonist: "You're such a dork."
Clarinetist: "At least I've got a girlfriend, you bassoon."
Trombonist: "Ouch, no need to get nasty."
