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.

An activity involving a woman 74 years old or older (Halley’s comet comes every 74 years) where the male is having sexual intercourse with the female “doggy style” in the anus. After he releases his blessed seed in her anus he pulls out where as the the female immediately farts and reaches behind and lights the fart, hence, releases the flaming comet on the poor unfortunate male with a beautiful glistening trail following behind from his seed. Extra points if her name is Halley.
Example: Joe was fornicating with Alexandria when he orgasmed and she released a Halley’s Comet on him that the world has never seen making Superman himself blush yet grow stronger........
