Temporal Pedabation
The act of travelling back in time to molest oneself as a child. This activity raises several questions, is it masturbation since it is you? Is it pedophilia since it is a kid? And what's more pschologically damaging, being molested or growing up to realize it was you?
Marty got so wound up the other night talking about temporal pedabation,he got in the delorean and fucked himself in the ass after his 7th birthday.
