The 'Wat' meme, also known as 'Wat Grandma,' features a close-up image of an elderly woman with a look of utter bewilderment and shock. Originating from a photograph that surfaced on the internet in the late 2000s, it quickly became a staple reaction image on forums like Reddit and 4chan. The meme is typically used to respond to nonsensical statements, strange stories, or digital content that defies logic. Its longevity in internet culture is due to its universal relatability—everyone has encountered a situation where the only appropriate response is a simple, wide-eyed 'Wat'.
