What is the definition of Permalink Weapon?

A permalink weapon is like a super-powerful, yet utterly useless link that connects to a single, specific page on the internet, like a GPS that only knows your destination but can't tell you where you're going next. It's the internet equivalent of a broken GPS that leads to your favorite pizza place every time, but only because you've forgotten your current location.
