Physical and emotional symptoms normally representative of a drinking hangover, but which occur from auditing too late, particularly in busy season.
Guy #1: "Oh man, I was here drafting that long-form audit summary memo until 3:00 this morning. I've got a massive headache, sensitivity to light and sound, shakes, dizziness, and an overall feeling of regret for what I did last night."
Guy #2 "Shit, sounds like you've got a serious audit hangover. Nothing that 4 ibuprofen and a Red Bull can't fix, though."
