کس

Kos is generative. Few profane roots in any language produce as many living compounds. کس‌شعر (kos-she'r, "cunt-poetry") means bullshit. کس‌مغ (kos-magh, "cunt-position," sometimes spelled kos-magham) names a useless inflated office, frequently aimed at state appointees. کسم (kos-am) is exclamatory frustration. The morpheme is so productive that learners need to recognize it just to parse half the spoken-Persian profanity around them.
