The comet shit can be defined as a large hard turd (sometimes nearly perfectly round like that of a donut hole) followed by a spray of loose diarrhea. When defecating, often times the thrust necessary to push this initial round turd "out" creates a rocketing ball of feces followed by a shower of watery slime.
Dude, my guts are bubbling. I feel a Comet Shit coming on..
