A pootine is the excremental routine one follows. For instance, one may use the lavatory upon arriving home from work every day, or immediately after waking up.
People can become highly distressed and irritable if their pootine is interrupted, and may begin to experience stomach cramps and/or feel bloated.
"The boss made me work overtime last night and it nearly killed me. I mean, the guy totally screwed over my pootine!"
"Now that I'm taking these evening yoga classes I'm going to have to change my pootine, the last thing I want is to have an accident while attempting the cobra pose!"
