Quoted from FunWithBonus:
. When a ball drains and rolls backwards far enough up the outlane until it hits a coil switch that activates an outlane ball saver that puts it back into play. For example, I've seen it happen a lot in Firepower. It's like an extreme reverse Lazarus ball, but the kicker back into play makes it extra awesome and makes me think it needs a name! I think this is one of my favorite things to see happen in pinball!
I call that a Resurjection. Maybe Rezejection. I never tried to spell it before.
