too much sausage in the gumbo

Mainly applicable to hot tub parties, but can refer to any social gathering which has a greater than 3 to 1 ratio of males to females. Based on the generally accepted practice of mixing seafood (particuarly oysters, which resemble female gentalia when shucked and slightly cooked), and sausage (no explanation needed), 50-50 in a gumbo stew. This phrase is best understood, and thusly used for humorous purposes in southern parts of the U.S. where people make and eat gumbo on a regular basis.
