With the appearance of software that can detect plagiarism, those who are too lazy to compose their own prose have been forced to take steps to try and avoid detection. Thus the word ‘rogeting’ has entered the lexicon, coined by a lecturer in business information systems who found strange phrases in his students’ essays.
Rogeting stands for the practice of replacing phrases in the copied text with alternatives from dictionaries so as to fool the software. This can lead to humorous results since the alternative may not match the context of the original, and can result in replacing “to stay ahead of the competition” with “to tarry fore of the conflict” and “more powerful personalised services” with “Herculean personalised liturgies”.
And what about “sinister buttocks”? It apparently originates (somehow) from the phrase “left behind”. That would actually make a good description of the series of bizarre but best-selling Christian fundamentalist novels about the rapture called Left Behind.
