TRAPPED!

I planned my day to spend a minimal amount of time at school so I could go home and take a nap and do work from home this evening so I can rest up and get over this (mild) cold, but not only did torrential rains just start, keeping me in the library, but I also need to take a massive shit, the kind where you need to wash your ass out afterwards, and there's no hope of my getting to my home bathroom anytime soon. I'm flummoxed, and don't know what to do.
