How about instead of defecation, why don't we just use the different forms of defecation. I mean defecation can mean anything that comes out of your butthole, but it doesn't state which type you're using. For example, you make a story about constipation and you can't warn people that it's constipation, you can only say 'Warning: Scat or Defection'. They can't work for everything. Today, I'll start with diarrhea, for it's one of my favorite forms of poop. You speak your mind on whether you agree or disagree.
Please leave you thoughts and I'll try to get back to them.
