I'm not aware of any such specific story. Football is a sport that should be inclusive and respectful, and any form of inappropriate behavior goes against the spirit of the game. Gay football players should be treated equally on the field and not be associated with improper actions.
Reiner did die in the manga. His death was a result of a series of events and conflicts that had been building up throughout the storyline. It had a major impact on the plot and the other characters.
Pulp Fiction is a complex and iconic movie with a lot of memorable characters. However, Zeke and Zeb are not characters that are typically associated with it. It's possible that there is some sort of misinformation or a very niche interpretation where these names are related, but in the general understanding of the movie, they don't exist within its world.
One popular Zeke and Luther fanfic is 'Adventures of Zeke and Luther: The New Beginnings'. It focuses on their new skateboarding tricks and challenges in the neighborhood.
Well, I've watched Pulp Fiction quite a few times, but I don't remember any characters named Zeke or Zed. Pulp Fiction has a complex web of characters and storylines. The main focus is on the criminals, their interactions, and the events that unfold in a non - linear way. It's possible that these names are from some sort of extended or fan - created content related to the movie rather than from the movie itself.
