cigarette principle - noun phrase - The phenomenon in which, if you want something to happen sooner, you should do something that will immediately inconvenience you during the act of that something occurring.

Generalizes effectively.

software installation roulette - The practice of piping the output of a web browser or other HTTP tool directly through a system shell, usually as root to install something important. The danger is that you don't know if the shell script has anything nefarious in it (such as rm -rf / or the installation of a rootkit) and by the time you find out it's far too late.
For example: sudo bash -c "$(wget -q -O- https://totally.legit.example.com/install.sh)"

smoke and mirrors system administration - noun phrase - When you bring a problem to your support team and they go silent for hours to days at a time. No amount of poking and prodding is sufficient to get anyone on the team to respond to your requests for status updates. When they finally get back to you they say that nothing's wrong and you must have made a mistake. Your thing is now unbroken. They never tell you (or anyone, for that matter) what they fixed or how they fixed it.
quantum documentation inconsistency principle - An axiom of corporate life in which there will always be more than one piece of documentation for something, all of the documentation will be measurably contradictory, and none of the procedures will work anymore.
