Paralelepípedo is the Portuguese word for a parallelepiped, and in Brazil it is famous as one of the longest, hardest words children meet at school. Because it is so awkward to say quickly, it has long been used in tongue twister jokes, spelling challenges and classroom dares. Online, recordings of people shouting it became a recurring meme format, with the comedy coming from the struggle to finish the word. This stretched scream version spread on soundboards as a reaction clip, kept alive because the word itself sounds funny even to listeners who do not speak Portuguese.
