Get the Buttwhanger mug.
An extremely loud fart, sounding much like a trombone. By varying the tension of the anal sphincter, a skilled butthornist can change the pitch of the resulting notes over a full octave.
Billy blew the butthorn, he blew it long and loud.
It made a great impression on the women in the crowd.
Some peed into their purses. Some peed upon their hands.
And Billy got invited to play in many bands.
