One who is fearful of others stealing their job. A person who needs to gain information about a coworker in order to
a.use it against them
c.stroke their ego by knowing anything and everything.
Often times they're seen removing their glasses in an effort to look busy and/or important, carrying paperwork and walking briskly as if they're in a hurry.
They will usually preface their response to the question "how's it going" with a large 'sigh' or 'exhale' and will continue walking past and turn slightly in your direction spewing 'work jargon' at you in an effort to seem extra busy.
"uh oh, Rat Engine is coming, QUICK HIDE"
"Rat Engine tried to make me look bad in front of my supervisor today."
