The idea is real simple. Take a movie, book, comic, etc. and change a word in the title to totally create something new. (And you can explain the new creation, if you want)
Example :
Star Trek 2 : The Wrath of Shawn - The crew of the Enterprise face their deadliest mission after forgetting to tip their barista at InterstellarBucks! Now Shawn is chasing the crew across the galaxy for his 15% tip.
