Top definition
The resulting expulsion and harmonic tone of fart while partially immersed in water. A duck firing a machine gun and quacking at the same time but without the machine gun noise will sound very similar. The noise is caused by the film of water between the buttocks that produces excess surface tension. When the gas passes through this matrix of abnormal conditions it reverberates to and fro causing the machine gun burst noise. This is a particularly good fart as the residue is mostly washed away.
