I was with you until "because they want to carry on searching ebay, scamming $someone boasting about network speed, or just plain getting shitfaced.", but I'm guessing you're just being cheeky.
I was thinking it was a BOFH ("Bastard Operator From Hell") reference. [0] The BOFH is a fictional sysadmin who is worse than any you have ever had, in entertaining ways. He basically does exactly the things the OP mentioned, while dealing with clueless management, undeliable vendors, and a Sith Apprentice^W^WYoung Coworker who learned well, and is constantly trying to stab him in the back. He's like a mix between Catbert and Wally. ;)
