دیوث (Dayoos)

“cunt, pussy”

The vulgar Persian word for vagina — the root of an enormous profanity family. 'Kos' by itself is crude but it's the derivatives that make it devastating: koskesh (pimp), kos-e naneh (mother's cunt), kos nagu (don't talk shit), kos khol (vagina-brained/idiot). Understanding 'kos' unlocks half of Persian profanity.

“dishonorable, scumbag”

'Nāmus' is one of Persian's most loaded concepts — it means honor, specifically family honor tied to female relatives' chastity and reputation. 'Bi nāmus' (without nāmus) is therefore one of the worst things you can call someone: a man who has failed to protect his family's honor, or worse, doesn't care about it.

“shitty, dickish, crappy”

The all-purpose adjective form of 'kir' (penis). Anything terrible, worthless, or pathetic can be 'kiri' — a kiri car, a kiri movie, a kiri day. It transforms the penis from a body part into a quality rating system where everything associated with it is garbage. One of the most frequently used adjectives in vulgar Persian.

“to piss, to pee”

The vulgar verb for urination. Figuratively, 'shāshidam be X' (I pissed on X) means extreme contempt or disrespect. Less harsh than 'ridan' (shitting) but in the same contempt family. 'Shāsh' (piss) as a noun also means something worthless.

“dishonorable, lowlife, scum”

Literally 'without sharaf' (nobility/honor). While similar to 'bi nāmus,' this targets general moral character rather than specifically family-sexual honor. A 'bi sharaf' person is a liar, a cheat, someone who breaks promises — dishonorable in the broader sense. It's a serious insult but less explosive than 'bi nāmus.'

“cheapskate, miser, tightwad”

Stingy, miserly — someone who hoards money and refuses to share. In Iranian hospitality culture, being 'khasis' is a character flaw that borders on moral failure. The Arabic-origin word carries weight: it's not just 'careful with money,' it's a fundamental deficiency of generosity that makes someone socially repugnant.

“bastard, asshole, wrong'un”

From 'avaz' (exchange/substitute), implying someone who shouldn't exist — a 'replacement' child, a mistake. In modern usage it's simply 'bastard' or 'asshole' without the literal illegitimacy implication. It's one of Persian's most versatile general-purpose insults for someone you despise.

“motherfucker / fuck your mother”

A highly offensive term attacking a person's mother directly through crude sexual imagery.
