A vile sexual act in the same vein as the Cleveland Steamer
or the Alabama Hot Pocket
. To properly perform a Puget Sound Sausage, the male must excrete a good deal of liquid diarrhea into the toilet while his partner is unaware. Once the water is good and brown, the male dips his phallus into the diarrhea/toilet water mixture, then runs outside and sticks his member into his partner's mouth before he/she realizes the penis is covered in diarrhea.
