Finger in mouth. Get all nice and wet. Teeth on bottom side of rings. Pull and twist adding saliva as you go.
It's the trick we had people do in the ER before bringing out the cutter or sending them for the laser (for tungsten steel, they have to be laser cut off, regular cutters won't work).
Sex lube can work as well, but getting a grip on the rings is almost impossible with any kind of tool, and lube just tastes disgusting.
