Surströmming is fermented herring from Sweden, while durian is a Southeast Asian fruit, and both are widely known for their powerful smell. Online, creators often pair extreme foods for shock value, taste tests and reaction videos, where the humour comes from anticipation and visible disgust rather than flavour. This clip follows that pattern, using the Spanish phrase for the combination as a shorthand for something almost unbearably smelly. It remains useful because the joke needs no translation of the foods themselves, only recognition that both are famously pungent.
