false flag wanker

Someone who goes on social media and labels a terrorist attack/shooting/bombing as a false flag attack within minutes of it occurring and having literally no information about the event.

News: Reports are coming in of an explosion in a building in downtown LA. Details are sketchy at the moment but it is possibly a burst gas main.
False flag wanker: It's definitely a false flag attack, I better get on facebook quick to let everyone know.
