I watched it again, and I honestly don't know what it is... I may need to watch it again... and again... and again...
her ass is really hypnotizing though. The whole damn thing is. And what the hell is Dead Snow?
Foreign film about Snow boarding group of friends that somehow awaken Nazi zombies, chaos insues. Seems the place of they chose to snowboard used to be a nazi stronghold.
I think the swinging of her ass and the fact she keeps repeating "my ass" is how she has been hypnotizing you.
