It was the ancient V of Rassilon, the greatest and rudest insult of the Dark Times. The script beneath read in Old High Gallifreyan:

Though remarkably flexible in its usage, this word is unfortunately untranslatable from Old High Gallifreyan into Earth English. Very roughly speaking it conveys disdain, contempt and extreme annoyance, all wrapped up in a generally obscene etymological parcel that is far ruder than any reader of this book can possibly imagine. For this reason it has also been deleted from the Matrix.
