The Ragdoll Effect

Ragdoll is a simulation of physics which causes the character to function like a rag doll, e.g. falling to the floor or being dragged by something pulling it.

Examples for Ragdoll:

In the game Skyrim, the characters enter a Ragdoll state when they die.
In the game Rag Doll Kung Fu, you control only one part of the character’s body, and the rest of it follows this part like a rag doll/
