a slippery doo da is when you fuck a girl hard in the ass then you eat all her hair on her scalpe until she is bald then you let her shit on your eye lids as you blink her shit gets into your eyes. then she makes out with you while you both have her shit in your moufs. It is also known to be done with dogs,cats,mouse any small woodland animal would work nice. and if you really want to get down you can use a elephant. some people like to kick it up a notch and get knives and cut open there partners insides and have sex with there internal intestines
