The 'I Just Hit a Dog Going 70MPH on My Truck' meme is a prominent example of 'bait-and-switch' or 'shock' humor within the shitposting community. It typically features this jarring, tragic sentence used as a caption over completely unrelated imagery, such as upbeat anime characters, furry avatars, or dancing videos. The humor stems from the extreme tonal dissonance between the text and the visual, mocking the way some social media users overshare traumatic events or simply aiming to catch the viewer off-guard with surreal, dark absurdity. It has become a staple of ironic internet culture, often used to derail serious threads or to create confusing, high-energy shitposts.
