Cheggarrhea 

When a student uses Chegg for homework and blindly copies homework without knowing what they're doing. Then when they take a test their work looks just as bad or worse than diarrhea.

Professor: This student's test looks awful. He must have used Chegg because it looks like Cheggarrhea.

What you get when you drink so much water, that it gives you diarrhea.

I got explosive chugarrhea from drinking too much water during cross-country.
