look up any word, like bukkake:
Noun. The art of recieving a blumpkin while the toilet is clogged or stuffed, and the water is in the top of the bowl. When feces are released, the increase in volume requires the toilet water to be expelled on to the face of the person giving the afformentioned blowjob.
My buddy clogged the toilet when he flushed the baby down there, and the water was going all over the place. My dirty bitch went down on me anyway and she gave me a splash blumpkin.
