Clean the slate 

When consecutive bouts of diarrhea cause you to blow up the bathroom, leaving your bowels devoid of any contents and about as clean as they were at birth.

Person 1: Holy shit dude, you look like you lost 10 pounds.

Person 2: Dude, you have no idea. I had four massive rounds of the shits last night and only got 2 hours of sleep. I can't think of a better way to clean the slate.
