Aw, "go die" is sort of mean.

My husband's sister once pantsed him in public, and I still think this is one of the most potentially embarrassing sibling pranks I've ever seen. This brother-sister pair are going to love laughing at this together when they reconcile twenty years from now. Apparently, what happened is that redditor tyler123321's sister stole $20 from him, and to get back at her, he put this set of files on her USB card. That way, she wouldn't realize what he'd done until she got to school to do the presentation, and then she'd have to scramble to find her project.
