Halley’s Comet (n): a euphemism for the violent projectile formed when a man cumshots a kidney stone. Not to be confused with commonplace occurrences like the ‘cum cork’ or ‘poop noodle’, the Halley’s Comet is a once in a lifetime experience characterized by:
(1) the catastrophic release of pressure necessary to cause a kidney stone to exit the urethra with a minimum muzzle velocity of 500 ft/s (152.4 m/s in CommieSpeak). The terminal ballistics of any given comet is determined by both the mass of the stone and the anger placed into the cumshot.
(2) the signature formation of a white trail of liquid aerosol cum behind the comet which lingers in the air for several minutes, causing it to be dubbed ‘procreative napalm’ by Single Mom’s Magazine.
There are no reported fatalities from direct Halley’s Comet impact (in the 1st world) however they do account for over 1 domestic ER visit a day in the US alone. Halley’s Comets are the leading cause of PTSD in men over 40.

Psychologist: “Tell me about your most recent Halley's Comet ”
Patient: “Just like the other ones, my dick looks like a waffle cone... My neighbors flipped out on me because they thought I intentionally shot their dog with a bb gun, then when I explained that I accidentally killed their dog with my exploded bee-hive looking dick, they just freaked out like I said something ridiculous.”

A Halley's Comet is a particularly large, compact bowel movement that is so efficiently delivered to the toilet that it does not require any toilet paper whatsoever for clean up. The term "Halley's Comet" suggests the rare nature of this achievement... likely to genuinely occur only once or twice in a lifetime.
"Man, what a wicked dump. Felt like a Halley's Comet, but it turns out I still needed some toilet paper."
"I ran out of toilet paper last night. Fortunately, I had a Halley's Comet this morning, so I was good to go."
"That was the most satisfying shit I've ever had. Pure Halley's Comet. I hope I have another one in the next 80 years or so."

A sex act where the man sits on the toilet facing the tank with his partner (easiest achieved with a female partner) on his lap having sexual intercourse with full penetration and while the man humps his partner the partner is making a bowel movement (hopefully into the toilet as to reduce cleanup)
