A true shit show that involves dipping your wiener into the nether regions of a colostomy hole. The name can be broken down to incorporate a few sub levels of innuendo; the prefix "bag" references the poo bag that must be removed for the activity. Also the "shuffle" relates to the shuffling motion of removing the poo bag and shuffling your soon to be chocolaty dink in and out of the hole as well as a kind of dance. And finally, the place "Baghdad" maintains relevance insofar as that dropping turds in public places is generally accepted there and is considered by many to be the shittiest place on earth.
Baghdad Shuffle: My fuck, are we in Calcutta? Stop Baghdad Shuffling, you're getting shit everywhere.
