If you have a sibling, you already know that an intense sibling rivalry is inevitable. And sometimes, it goes way beyond playful teasing. Siblings are infamous for pulling pranks on each other, but there’s definitely a fine line between harmless fun and pure sabotage. And siblings always seem ready to push that boundary. 

Take prom night, for example. For teenagers, it’s basically the red carpet night of high school. Every little detail feels like it could make or break your social standing, from your date and your outfit to those cringey photos that live forever on social media. Everyone’s awkward, everyone’s stressed, and the stakes feel higher than they actually are.

Now, imagine having your entire night ruined by your own sibling.
