What about another one: "BadStuff"? I use that term so much that some non-technical colleagues *must* think that it's an OOP term by now...
As in... "if you spell the command wrong, the error handler kicks in. If you use the wrong command, BadStuff occurs."
The whole problem with the world is that fools and fanatics are always so certain of themselves, but wiser people so full of doubts. - Bertrand Russell
