To investigate what your co-worker that you don't like is doing so you can hate on them for succeeding.
A car salesmen walks by another salesman's office to evesdrop and find out if the other salesman's customer is going to buy the car. If they buy you can hate on him. If they walk out without buying it makes you happy that he failed. "Hold on Jim has a customer. Let me go investihate."
