IT departments have had a long, sometimes deleterious and mostly fun-filled history of making up nicknames for clueless, overwhelmed and tech-challenged users of IT software and hardware.\nOne of my favorite derisive terms is a calling a user a \u201cluser.\u201d Good one.\nAnother one that I\u2019ve recently latched onto is \u201cPEBKAC\u201d\u2014problem exists between keyboard and chair. Zinger! \nHow about this one? UBD: user brain damage. Nice. \nOr this old acronym, which has a different (if still toxic) use these days: DDT. That is, \u201cDon\u2019t do that,\u201d which is usually in response to a user who just said, \u201cWhen I do this....\u201d \nThis one was new to me: \u201cWetware,\u201d referring to the source of some type of user-introduced error. There\u2019s also the \u201cid10t error,\u201d and the less biting \u201cLuddite.\u201d \nThis antagonistic relationship between IT and users has been wonderfully parodied by Saturday Night Live\u2019s skit \u201cNick Burns, Your Company\u2019s Computer Guy,\u201d played by Jimmy Fallon. (A couple of my favorites are on YouTube, including Nick and his dad (Billy Bob Thornton) and Nick and a smart user (Jamie Foxx).) His three catch phrases typify horrible IT and user interactions: Nick Burns shouts, \u201cMove!\u201d whenever he commandeers a confused user\u2019s keyboard; \u201cWas that so hard?!\u201d is his sarcastic remark when he fixes the problem; and \u201cOh, by the way, you\u2019re welcome!\u201d is the snarky way he exits the room after he has easily solved all of the lusers\u2019 tech problems. As someone who has committed many idiotic computer transgressions over the years, I find the simmering animosity between IT staffers and the user base fascinating and mostly funny. (The legendary story of the user trying to use his CD drive tray for a cup holder justifiably lives on.) Still, many people feel that derisive IT comments widen the divide that IT sometimes drives between itself and other non-IT staff, according to an unscientific gathering of user opinions among my colleagues and friends. \nWe\u2019ve tried to figure out the whys and wherefores of this dynamic on CIO.com from time to time, as in Why IT and Users Hate Each Other and Users Are Right to Hate IT, or Time to Rethink Your Relationship to End Users and Why an Autocratic Approach to User Support Will Fail. \nWhatever the case, you can\u2019t deny the adversarial vibe and the occasional wit that results. So what other names have you heard IT use to identify clueless or annoying users? Let\u2019s see what you can do.
