If you’re unfamiliar with Chatroulette, the website allows people with webcams to be matched up with strangers for some random social interaction. Not working quite as planned, the site has built a reputation for offering up a whole lot of lonely men (often “in all their glory,” if you know what I mean) ready to show off to the lucky ladies who find themselves regrettable staring back.

In a work of genius viral marketing, the new horror film The Last Exorcism decided to take advantage of this situation. They put together videos of beautiful young women, who would appear to be ready to put on a show for the gentlemen watching her feed. Just when the girl looks like she’s about to remove her clothing, however, the eager male expressions turn to shock as her eyes roll back in her head, and a demon-esque creature comes at the camera.

Thankfully, there’s some videos of reactions to this unexpected horror, and you can head below to check them out for yourselves!
