Semiarrhea 

a digestive condition in which your stool has a consistency and form similar to diarrhea, but not quite as runny. Like diarrhea, also known to cause frequent trips to the bathroom. Can come in the form of beer shits.

I really needed to be productive today, but I had a terrible case of semiarrhea.

Skyarrhea 

That hideous mix of ice and rain when the temperature is between 31 and 33 degrees Fahrenheit, combined with a stiff Northern wind. It's as if mother nature is literally shitting on all of creation.

"Oh man, it's terrible outside. I've never seen skyarrhea like this before."

Skiarrhea

Pronounced similarly to Diarrhea, the Skiarrhea is a move only few can pull off.

Whilst skiing with an upset stomach, one must start by "dropping trou". Keep in mind you would still be moving at this point. You then spread your skis apart and lower your ass cheeks close to the snow. Hover your ass cheeks close to the snow and let the shit fly. If done correctly, you should leave a nice brown streak on the ski run you are performing on.

Also keep in mind:
1) The Skiarrhea is even more fun if trou is dropped RIGHT in front of someone
2) The runnier the shit is, the more awesome the streak will be.

DUDE You totally left a fat Skiarrhea streak in front of that guy!

Damn dude what did you eat? You owned that guy with your Skiarrhea
