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."
