Shitcalling

The act of calling someone while taking a shit. Usually done with the goal of grossing the other person out.

One who calls attention to problems people don't want to talk about, often in a fashion that offends others. Connotes a degree of righteous indignation or "uncomfortable truth".

The last call of the day, that usually ends up being a shit show and results in you being kept past your scheduled time off by an hour or more(usually a lot more). Usually always happens on a Friday. Or the last day of your scheduled rotation.
