beat you to oblivion

To savagely beat someone beyond the mere confines of life and death, to a point where an inter-dimensional portal opens up and, in a blinding maelstrom hot as a supernova, sweeps the carcass of the beaten person up into the atmosphere, breaking all known laws of physics, and leaving no trace of the beaten person behind.

Kingfish: "Uh, I lost all my money at the racetrack."
Sapphire (grabbing a rolling pin): "I'm gonna beat you to oblivion!"
