As Seen In: Sleepaway Camp (1983)
It doesn't get much more abject than this vicious killing from 1983's inventive Sleepaway Camp. Seriously, it puts all of Jason Voorhees' and Michael Myers' simplistic knife and machete homicides to shame.
Just as the above headline reads, Angela (Felissa Rose) gets her revenge on the camp bully, Judy (Karen Fields), by invading her vagina with a piping hot curling iron, after slugging her in the face to knock her down into helpless submission. Republicans must love this movie.
