The 'Before and After Looking up Why Chainsaws Were Invented' meme centers on the collective internet shock regarding the chainsaw's medical origins. Originally designed in the late 18th century by two Scottish doctors, the device was intended to aid in difficult childbirths by performing symphysiotomies—essentially cutting through pelvic bone and cartilage. This disturbing historical fact became a viral trend on TikTok and Twitter, where users document their transition from innocent curiosity to absolute horror. The meme usually features a split-screen or two-panel layout showcasing a 'before' state of bliss and an 'after' state of existential dread, serving as a dark commentary on the hidden history of everyday objects.
