Traditionally done when two men (typically homosexuals but not always) are given a blow job from the same person. In order for both of their genitalia to line up they get into a scissor position with balls and dicks touching. This way the sucker can get both dicks in his (or her)mouth at the same time.
Hey Jeevan that guy over there offered you and Jonny a double scissor suck because he thinks you’re both hot as hell.
