داد و بیداد

The pairing of داد and بیداد is older than the slang use, with both words rooted in the classical lexicon of justice and oppression. Hafez and Saadi both lean on these terms in poems about cosmic unfairness, where داد and بیداد form the moral backbone of the verse. In modern conversational Persian the pairing has softened into the everyday "big fuss" sense, with the original political-poetic weight surfacing only in literary contexts. The compound structure is itself classic Persian: pair a word with its rhyming opposite to make a vivid abstract noun. Listen for the same pattern in نان و آب ("bread and water," meaning livelihood) or خواب و خوراک ("sleep and food," meaning the basics of life). The structure is everywhere once you start hearing it.
