This is a 3.4-second voice clip of Antonio Gasalla as the elderly Mamá Cora character delivering a furious Spanish insult, Vieja de mierda, la puta que te parió, in a shrill, outraged tone. It feels rude, funny and instantly cathartic, like a grandmother losing all patience at once. The line comes from the Argentine film Esperando la carroza.
