Of AnCom origin, the term refers to graffiti where in "Liberals get the bullet too". This was shortened to "They will get it too" then simply "Geddit". It is an implied threat against anyone who the individual stating the term thinks of being an enemy of "The People". In short, "When the revolution comes, X will be killed."
