A post says
Can you show me on the doll where the bad data management expert touched you?
Wiki gives this explanation about "on the doll"
The film's title comes from the phrase "Show me on the doll where you were touched", often asked of young children who have been the victims of sexual abuse. The film covers multiple lives of victims and victimizers, sharing the pain of how early childhood traumas can continue throughout adult lives.
I guess I understand the explanation. The question is about the usage.
When would someone said something like that to another person, besides the actual police-victim situation?
Would the use in first quotation be considered as an interesting expression, or some kind of impolite?
