A coworker who seemingly spends his entire workday visually immersed on meaningless activities while all of his collegues are extremely busy working on real business. His outward appearance suggests he is diligently involved in some pertainent project when, in fact, if the contents of his screen are inspected, it becomes quickly apparent that he is just putzing away the hours on some usless bullshit. Usually the putz master is a nice person and has been put into a position that intellectually they are unable to perform so the coworker is confused as to whether they should help support his pitiful facade or alternatively end it all in the parking lot.
Coworker: "Hey, what have you been working on all week?"
Putz Master: "Ah, well, some import stuff. I'll show it to you next week".
Coworker: (under his breath), "Fucking putz master"
