brinksmanshit
When two or more parties have entered separate bathroom stalls at nearly the same time and deliberately delay moving their bowels so as not to be the one to break the often awkward and intense silence.
We had made but a single but profound error in making eye contact before entering our stalls and now we were paying for it, sitting a mere 3 feet apart, separated by only a thin metal barrier, undoubtedly staring at each other's shoes, locked in a treacherous game of brinksmanshit.
