Halley's cumet 

When two guys face each other, at least 1.5' apart, and cum simultaneously. If their cum meets in mid air the resulting explosion is known as halley's cumet.

They say you should wear a raincoat and safety glasses when you witness Halley's cumet. After witnessing Miller and Cameron's I would have to agree.
