The Jugulator
A divisive 1997 album by metal band Judas Priest that features a robotic creature on the cover. A niche meme on 4chan claims that the Jugulator is real and is coming back. Jugularposting refers to invoking the Jugulator’s power to wish for something.
I hope the Jugulator comes for you first.
