The Razorblade Smile is the act of using MySpace, Facebook or other popular social sites to make give someone mild to severe mental distress or even lead them to suicide. This is done by creating a false profile, befreinding and or seducing them online, then turn on them in some horrible way. All the while never comming into live contact with the target.(Razorblade for them, Smile for you)
A woman posed as a teenage boy to seduce and ultimately destroy her daughter's best freind using the MySpace network. The girl she wrote to commited suicide shortly after the "break up". A true example of the Razorblade Smile..
