An edgelord is someone, typically on the Internet, who tries to impress or shock by posting exaggerated opinions such as nihilism or extremist views.
[1] 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.
[5]Edgelords were characterised by author and journalist 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.
