An anagram describing when two or more co-workers (colleagues) are suddenly absent on the same day due to cooties. This may be from the fact that they work together (or are best friends) on a daily basis and contracted the same bug (cooties).
Person 1: Where's Billy Bob?
Person 2: He's out for the day.
Person 1: Weird, because Billy Ray is also out for the day; they do work together so they probably came down with cooteague.
Person 2: Yeah bro, so where are the TPS reports?
