As Seen In: Sleepaway Camp 2: Unhappy Campers (1988)

Talk about adding insult to injury. In the sleazy horror sequel Sleepaway Camp II: Unhappy Campers, the homicidal Angela (Pamela Springsteen) lures the unsuspecting Ally (Valerie Hartman) outdoors with a faux love letter, "written" by a guy Ally adores. Once Ally is in her midst, Angela first stabs her in the stomach, which, by the end of the scene, almost seems friendly.

Rather than just let Ally bleed out, Angela pushes her victim's entire body into a grungy outhouse's glory hole. Inside the totally unsanitary toilet, Ally suffocates under mounds of feces as Angela relentlessly pokes her with a stick to keep her from escaping. Hopefully they have showers in heaven.
