People have a weird fascination with doing gross things in a safe way. It's experimenting and pushing boundaries. It's hard to get noticed doing something ordinary and that is the very reason we’re always looking to shock, to make people murmur or point fingers. There's no bad publicity and every reaction will serve the purpose of engagement. It's a perfect Halloween desert where little oddities are a welcomed sight. Outside of this holiday its something you can scare your poor grandmother with.
