Get the Betrayler mug.
When a trailer for a movie movie totally and clearly betrays the source material pissing of fans everywhere right and left and scaring away people from the original because it's soo shitty!

Basically like anything Uwe Boll made or anything similar.
person a: Did you see that trailer for <insert title here>?
person b: yuck! yeah total fucking betrayler! fuck that shit!

I'm gonna re-read the book and pretend that shit was ever made!
person a: Yeah fucking sell out corporate dushturd holywood!
