Maria Clara Alarcão is a Brazilian feminist and former pornographic actress known for her controversial "Sanduíche de Buceta" (Vagina Sandwich) video, which has become a classic meme and a staple in Brazilian internet culture. The video, which dates back to the early 2000s during the heyday of Orkut, the once-popular social networking site, features Alarcão in a provocative and explicit scene involving sandwich and mayonnaise that has since become iconic.
