Senior 

The highest possible rank in the high school hierarchy. Fourth years are the best of the best - they've survived three years of being mocked by the grades above them and are determined to make the three years below them suffer the same way. They've got power, connections, sometimes weed, and a shitload of exams coming their way, which they'll likely either completely ace or completely fail.

Guy 1, pointing at another guy: Who's that?

Guy 2: That's a senior. I don't remember his name, but we should bow while he walks by or he'll get his connections to murder us.

Guy 1: Oh shit.

Senior Assassin 

A game created by a student from Salem high school in Virginia Beach, Virginia.

The game consists of a group of high school seniors ONLY, who are all assigned targets anonymously. The point of the game is for an assassin to eliminate their target with a small water gun before each round ends, which is 7 days. They MUST submit a video of the elimination to the senior assassin instagram page for their targets elimination to count.

The game can be changed each round with new challenges, such as if an assassin eliminates their target in a specific amount of time, then they can informed on who their assigned assassin is for that round.

In the game if you’re wearing goggles on your face, or floaties on your arm then those are considered shields.

Assassins cannot elimainate their target while on a shift at work, in school, or on school property, OR during any school events (such as prom, or before prom).

Girl: Hey, have you signed up for senior assassin?
Boy: Yeah’! It’s so fun watching the eliminations on their Instagram!

Girl: I know!!! I’m about to go elimate my target before they have work. A
