Analogous to re-booting your computer, a re-boot day is when you call in sick to re-boot your sanity. It usually involves leaving someone hanging at work that is depending on you, but your brain is so fraged you can’t function any longer.
That F'in Korbegli left me hanging today on our project.

Yeah, he blue screened after the meeting yesterday and said he needed a re-boot day.
