The 'The Devil Shivers When A Nice Guy Loses His Temper' meme stems from an unironic edgy quote that surfaced on social media platforms in the early 2010s. Typically associated with the 'Nice Guy' persona, the phrase gained widespread popularity as an ironic trope on platforms like Reddit and Twitter, often paired with images of the Joker, skeletons, or anime characters. The humor lies in the contrast between the melodramatic, threatening nature of the text and the often non-threatening reality of the person posting it. Today, it is a staple of cringe-culture and internet irony, used to mock individuals who believe they possess a suppressed, dangerous dark side.
