They are making new versions of the Star Wars films. The names have only just come out.
There is Star Wars: Attack of the Trannies, Star Wars: The Trannie Awakens, Star Wars: Rogue Trannie, Star Wars: The LGBTQ Strikes Back, and then there is Star Wars: The Last Straight Man.
Listen up, buttercup. This joke is all about taking the piss out of "Star Wars" by giving the films titles with "trannie" in them. It's supposed to be funny because... well, because some people think it's hilarious to make fun of transgender people. As for you, you probably think Jar Jar Binks is the best character.

This makes no sense, that’s why it’s funny
