The Bullshit Detector meme acts as the ultimate digital referee for calling out falsehoods, exaggerations, and blatant lies across social media. Typically featuring a physical gauge, a handheld device, or a character reacting to a dubious claim, the meme visually represents the 'BS meter' hitting red or exploding. It gained popularity as a reaction image used in comment sections to debunk fake news, mock corporate PR statements, or simply tease a friend about a far-fetched story. The template is versatile, often paired with text describing a scenario where someone’s words clearly don’t match reality, making it a staple of internet skepticism and humor.
