turlingdrome.
Yet another classic word from the genius of Douglas Adams (read the books if you haven't already). "Turlingdrome" is a word known throughout the Galaxy as a grave insult, equalling the insulting insultiveness of such words as "swut" and "joojooflop." Thankfully, however, it doesn't even come CLOSE to that deadliest of all words: "Belgium."
Enlightened HG2G Reader: "See that guy over there? He's never even picked up the Hitchhiker's Guide, the turlingdrome. He probably doesn't even have a towel."
Random Unenlightened Non-HG2G Reader: "Er, pardon me, but what the hell did you just say?"
