A controversial message that has been popping up on dollar bills and coins around the world. People on facebook and other social networking/blogging sites are speculating that it's related to some sort of anarchist uprising and others say its just a hoax.
Although "5/19/13 expect us" is mostly just discussed as being a seemingly intentionally vague message being written on banknotes people have reported seeing it written in the form of graffiti in highly populated urban areas which suggests that it's related to the underground culture particularly in the United States.
