This is called being rolled by a train. You can see what it means to literally be rolled between a stationary surface and a moving surface.
Somewhat related to beekeeper lingo where the worst thing you can do in your hive is to roll your queen.
Means giap the queen between comb panels and rolling here round and round when the panel is pulled.
This kills the hive.
Much like this kills the person when a train is involved. Every substantial bone in the torso is probably smashed and every organ unhinged and punctured by the bone fragments.
