I keep being drawn back to my roots as a fan of "genre" related art. Books, short stories, movies. There's not a ton of genre-related poetry (that I've found). So we're going to work on it.
Let's start with a horror poem. Or at least one that deals with horror and/or its tropes.
Note, this doesn't mean it has to be a scary poem. Even if it is, you set your own rules for the fashion in which it's scary. Jump scares not required.
Pick a character archetype from horror movies: the Slasher, The Final Girl, the Cheerleader, the Nerd/Stoner, the Token Minority, the Best Friend/Nice Guy, Gordon Sumner (have you listened to Every Breath You Take? Dude's a serial killer waiting to happen).
Write a poem about them, or from their perspective. Bonus option: make them aware of their fate. How does it feel to be victim number one? Or the blissfully unaware (otherwise) side character?
