The 'What Did You Just Put In Your Pocket?' meme stems from the universal experience of being confronted while trying to hide a small, often forbidden or unnecessary item. Whether it's a toddler with a forbidden toy, a dog with a mystery object, or an adult 'borrowing' extra napkins from a restaurant, the humor lies in the immediate defensive denial that follows. It gained significant traction on platforms like TikTok and Twitter as a relatable format for showcasing life's most suspicious yet harmless moments. Users frequently adapt the text to highlight the absurdity of the items being hidden, turning a simple question into a comedic reveal of common human (and animal) quirks.
