Deadender 

A moviegoer who stays till the very end, through the credits. Motivation for such behavior includes the chance of a post-credits scene, paying respect to the many creators of the film, avoiding the crowd at the exit, waiting for one's skin and eyes to recover from a lacrymal profusion, pointing out unique names in the credits, enjoying the music, or just appreciating the dark.

"Just to warn you," she said, settling into her red velvet seat, "I'm a deadender."
"That's okay," he responded, reaching over and taking a handful of popcorn, "so am I."
