Night of the Demons 2 (1994)

A group of teens decide their school Halloween party is too tame. So they head out to Hull House, which has been abandoned since a massacre occurred there a few years ago. The teens awaken the demons who start killing anyone they cn get their hands on. When the kids try to escape, they accidentally bring the demons back to school by taking something with them from the house.

Now here's what I don't understand. One of the girls finds a lipstick on the floor of the bathroom. The house hasn't been lived in for years, but she decides to use the lipstick. Not only that, but she puts it in her purse for later use. Bleech!! Are you kidding me? Why would anyone take an old lipstick from an abandoned house? You don't know whose used it. That's just gross.
