diarradius 

The maximum distance that one can travel from from a given location to a preferred bathroom. The term is most often used to determine whether it is safe to consume food from a particular location. A diarradius varies as a function of the individual as well as the type of food that is consumed.

I can't eat at the taco truck on third street because it is outside my diarradius.

DIARRABIES 

When you have diarrhea so bad it drives you insane. You foam at the mouth and are afraid of water.

Ron: Hey Harry, what's wrong with Seamus?

Harry: I dunno, friend, he's been acting mad all day!

Hermione: Watch out! He has diarrabies! We have to put him down!
