portapotaphobic 

when you'd rather hold the urge to use the restroom rather then use a porta potty because of the smell, thee utter dread of the unknown walking into a porta potty, the germs, the wait, the lack of toilet paper, or the standing liquid mess around the porta potty ( be it mud, water from the cleaning crew, vomit, or urine and ??? leaking out on to the ground. eeek! )

i really have to go but i'm so dang portapotaphobic i'm not even risking it. i'd rather just hold it or run home.
