Any sexual encounter shared by three or more people simultaneously in which at least one of the involved parties is playing an acoustic instrument and receiving pleasure at the same time.
We played a show tonight at the local Stein and Deli, and then afterwards these three girls wanted to have a Menage of Twang with me at the after-party. All three of them went down on me while I played Freebird on the banjo.
