In Pulp Fiction, Joe Cabot is a significant figure. He is part of the underworld or criminal element that the movie portrays.

I'm not sure specifically what 'Cabot Benson Strapon Fanfic' is. It could be a very niche or specific piece of fan - created fictional work related to characters named Cabot and Benson, but without more context it's hard to define precisely.
I'm not sure which specific 'Sebastion Cabot ghost story' you are referring to. There could be many fictional or local tales associated with a person named Sebastion Cabot. Maybe it's a story passed down in a particular region or within a family.
