Bruja del 71 is the nickname for Doña Clotilde, the elderly neighbour in the classic Mexican sitcom El Chavo del Ocho, so called because she lived in apartment 71 and neighbours jokingly treated her as a witch. The nickname has lived on in Latin American humour long after the show, appearing in memes, remixes and everyday teasing for someone who seems secretive, eccentric or a little spooky. Short clips using the name work because the reference is instantly recognisable to fans, even without any dialogue from the original programme.
