A phrase used by seniors and middle-aged men to describe the
Intertubes.
Use of this phrase is generally considered an indicator that the person using it is attempting to appear hip while really out-of-touch with the zeitgeist.
In the UK the phrase has gained widespread
popularity among many readers of The Sun,
The Daily Mail, The Star and the Express. And therefore those using the phrase are often chastised for their old-fogeyness.
