Destroying your own reputation completely and irreversibly in a few quick steps. Usually refers to someone's great reputation that was built over a very long time and which was utterly destroyed in a very short time by their own unexpectedly ridiculous actions, like the previously-respected famous author Nicholas Nassim Taleb did to his own reputation after many consecutive aggressive rants on social media that many saw as complete mental break-downs and as attacks to his own ideas, books, friends, colleagues and followers. This is one of the quickest known "from Hero to Zero" in the modern world.
