symparrhea 

When you make fun of your buddy who is preparing for a colonoscopy and you wake up the morning of their procedure with the runs.

I shouldn't have taunted John about his upcoming colonoscopy. I woke up this morning with symparrhea.

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.

Sympatheating

Binge eating with a loved one to sympathize with them and their situation.

Last night I was sympatheating with my wife when I ate five packages of sour patch kids while she indulged in Reese's peanut butter cups from the Halloween candy.
