By telling you about the Pantienon app, I am taking a huge risk. While most of you will have the decency to read and forget about the Pantienon app, some will actually go and get this app for their phone (they are called perverts).
The Pantienon app is an iPhone application that lets the user create an image of a girl taking off her panties. The user snaps a photo of her legs and then the Pantienon lets you drag one of four different panty types over them, which makes it look like her panties are coming off. Disturbing.
