A pseudo-swear word (or probably meta-swear word given the nature of the cartoon)
that a certain Dilbert character that's so popular he's got his own cartoon likes to say.
The reason why I involved the whole 'meta' thing in this is that I believe that Dilbert is far too introvert to actually utter the word 'damn' or even 'darn' and therefore
resolves to only imply that it's 'naughty' by basically saying something that implies that it's a cussword. It's all very confusing IMHO
