A land-based comet formation of Welsh human origin.
The Cardiff Comet was first spotted in the Cottage pub, Saint Mary Street, Cardiff on 16th August 2010. It consisted of a fat woman followed by 5 or more women of decreasing size.

It is not known whether the smaller women were fragments of the larger women or individuals in their own right.

The Cardiff Comet is thought to be less predictable than celestial comets but is easiest to spot on a Monday night when only hard drinkers are out in Cardiff. There may a correlation with the hen night.

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.

A projectile that unintentionally flies out of your mouth when you cough. Typically, a piece of food which flies out and usually at an inopportune moment. Also known as a coughmet.
Last week, I was at a conference and Tony was introducing me to a potential investor. He was some Swedish guy and was snacking on some hor d'oeuvres. I was shaking his hand and I think something got caught in his throat because he coughed and something flew out of his mouth right at me. My catlike reflexes allowed me to dodge his cough comet as to avoid having a splotch of chutney land on my forehead.
