Edgelord
An edgelord is someone on the Internet who tries to impress or shock by posting edgy opinions such as nihilism or extremist views.The term is a portmanteau derived from "edgy" and "shitlord" – a person who "basks in the bitterness and misery of others".
Merriam-Webster gave the following example:We decided to watch It's A Wonderful Life and my dad said, “Every year I wait for Jimmy Stewart to jump off that bridge but he never does it” - merry Xmas from the original edgelord.
Edgelords were characterised by author Rachel Monroe in her account of criminal behaviour, Savage Appetites:...internet cynics lumped the online Nazis together with the serial killer fetishists and the dumbest goths and dismissed them all as edgelords: kids who tried to be scary online.  I thought of most of these edgelords as basement-dwellers, pale faces lit by the glow of their computer screen, puffing themselves up with nihilism.  An edgelord was a scrawny guy with a LARP-y vibe, possibly wearing a cloak, dreaming of omnipotence.  Or a girl with excessive eyeliner and lots of Tumblr posts about self-harm.  The disturbing content posted by edgelords was undermined by its predictability...
