Taco Truck Tammy refers to a viral incident from 2018 where a woman in Connecticut was filmed calling the police on a taco truck parked near her property. The video captured her questioning the vendor’s permits and became a prominent example of the 'Karen' trope, where individuals weaponize authority over minor or non-existent issues. Online, the meme is used to satirize people who act like self-appointed authorities in public spaces or neighborhoods. It serves as a sharp commentary on surveillance culture and the specific social phenomenon of calling the authorities on people performing everyday activities.
