A high level attitude common among many Information Technology personnel, technical support, software developers and similar professions. It is usually demonstrated by a great deal of arrogance, condescension, a propensity to offer insult and a strong emotional response to any perceived suggestion that a given problem is the result of an issue within 'their' code / network / database / realm of influence.

This attitude has been previously acknowledged in pop culture but never specifically defined (see Nick Burns, Saturday Night Live).
Vendor: "We've traced an communication issue between our application servers and your environment using Fiddler / Wireshark. It looks like there may be a problem with your proxy or firewall blocking specific files from our domain."

IT Rep (ITtitude): "There is absolutely nothing wrong with the Network. We are not having similar problems with other vendor software. Our proxy servers are configured based on industry standards and our local security policies. I refuse to entertain the possibility that an issue lies on my network. Please go back to your systems administrator and pursue a solution to this issue from your end."

User: Now I'm trying to do this quarterly and I can't get the stupid email attachment to open at all.

Nick Burns (ITtitude): Hmmm...it's the email that's stupid, not you..right?
