کس (Kos)
What does کس (Kos) mean? کس (Kos) is a Farsi (Persian) severe that translates to “cunt, pussy” in English.
Literal Translation
vagina
Meaning & Usage
"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.
Examples in the Wild
Rarely used standalone — almost always in compounds. 'Kos' is the building block, not the finished product. When used alone, it's either a crude anatomical reference or an exclamation of shock.
“این چه کصشریه دیگه؟ اعصابمو خورد کردی.”
“What kind of bullshit is this? You've gotten on my nerves.”
“کص نگو! خودت گفتی پنج میای.”
“No way! You said you'd come at five.”
“این کصخول بازی ها چیه دیگه از خودت درمیاری؟”
“What kind of stupid antics are you pulling now?”
“از دست این کصکشا هر روز یه مشکلی پیش میاد.”
“Because of these motherfuckers, there's a problem every day.”
“کص نگو! جدی میگی ماشین خریدی؟”
“No way! Are you serious you bought a car?”

Cultural Context
Kos is a potent and foundational Farsi profanity, rarely used in its direct form, but incredibly pervasive through its many derivatives. While "kos" on its own is a harsh and vulgar term for vagina, its strength lies in how it anchors a vast family of insults. Its direct use is still highly offensive, particularly in formal settings or when directed at women. Younger generations tend to use its derivatives more casually among peers, often as exclamations of frustration or disbelief, a slight softening compared to older generations who generally view any form of "kos" with strong disapproval. There isn't a strict gender divide in who uses it, but direct insults involving "kos" are often highly gendered in their impact, aiming to demean. The word's function is remarkably consistent across different regions of Iran, with its derivatives forming the backbone of informal, often aggressive, communication. You'll hear "koskesh" (pimp, motherfucker), "koskhol" (idiot, literally 'vagina-brained'), "kos nagu" (don't talk shit, no way), and "kossha'r" (bullshit) frequently. These are not just words but often entire expressions that convey a range of emotions from anger and frustration to disbelief or even playful teasing among close friends. The versatility of "kos" allows for nuanced insults depending on the suffix or context, making it a powerful linguistic tool. The unique power of "kos" in Farsi lies in its unparalleled ability to spawn an entire lexicon of profanity. It's not just a word for a body part; it's a linguistic launchpad. Think of it like this: if you understand "kos" and its common derivations, you've unlocked about half of the most colorful and impactful insults in Farsi. This makes it a cornerstone of street language, often found in Persian rap music or stand-up comedy (especially in uncensored forms), highlighting its cultural significance beyond simple vulgarity.

View all →بیناموس (Bi nāmus)
“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.
کیری (Kiri)
“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.
کون (Kun)
“ass, butt”
The standard vulgar word for buttocks/anus. It's the root of 'kuni' (gay, already in the database) and dozens of compound expressions. On its own it's crude but not devastating — more like English 'ass' than anything nuclear. 'Kun' generates much of Persian's anal-themed insult vocabulary.
کسکش (Koskesh)
“pimp, motherfucker, piece of shit”
One of Persian's nuclear insults — literally 'one who drags kos (vagina),' meaning a pimp. But nobody processes the literal meaning; it functions as a general-purpose extreme insult equivalent to 'motherfucker' or 'piece of shit.' Calling someone 'koskesh' is declaring them beneath contempt.
شاشیدن (Shāshidan)
“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.
بیشرف (Bi sharaf)
“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.'
لاشی (Lāshi)
“scumbag, lowlife, piece of trash”
From 'lāsh' (carcass/corpse), calling someone 'lāshi' means they're morally dead — a worthless, contemptible lowlife. It implies someone who does disgusting things without conscience. In Tehran street slang, 'lāshi' has become one of the most common character insults, covering everyone from petty cheaters to serious criminals.
دیوث (Dayoos)
“pimp / scumbag / bastard”
A strong insult implying a man is a pimp, specifically one who pimps his own wife, characterizing him as utterly without honor.
