The act of two or more women ducking on the head of a man's penis at the same time, as though they were fighting to be the one sucking in the head, but really they are working in unison to both have their mouths sucking on the head of the penis at the same time.
Look at that lucky guy over there. The three hot chicks are knobgobbing his cock.
