The 'Is Extremely Horny / Why Do You Cum?' meme is a surreal, glitch-style parody originating from 'Cyberpunk 2077' promotional footage. It features the character Johnny Silverhand, portrayed by Keanu Reeves, overlaid with absurdly edited UI text. The 'Why Do You Cum?' line specifically gained notoriety from a humorous 2020 YouTube mashup where the game's dialogue was spliced for comedic effect. The meme is typically used to represent chaotic energy, ironic horniness, or to mock the gritty, neon-soaked aesthetics of the cyberpunk genre. Its popularity persists on platforms like Twitter and Discord, where users enjoy the jarring contrast between the serious sci-fi setting and the vulgar, nonsensical captions.
