Person who combines slides from multiple sources into a single PowerPoint deck. Each source will not have a consistent approach to the slides or any competency in PowerPoint whatsoever. This combination will result in complex, complicated, overly detailed slides, and an excessive amount of mindless pixel by pixel movement to achieve a consistent presentation.
The person can sometimes be more concerned with having everything aligned and properly animated than the actual content of the slide or deck.
Since I was the designated Slide Monkey, I was up all night consolidating everyone's input into a cohesive deck.
