platypus-vagina blumpkin
The origins of this blumpkin is debated by scholars.  Dr L Funkenstein of New York's Blumpkin Institute believes it had its origins with the aboriganees of Australia.  While taking a squat in the creeks of Australia and being serviced by their significant other the vaginal lips became enlarged and turned blue because of the coldness of the water.  This resembled the bill of the duck billed platypus.  Hence the name platypus-vagina blumpkin.

Translation from Aboriganee:  Holy shit, look at the size of that platypus-vagina blumpkin.
