сися

Titty, boob (usually affectionate, childish, or mildly erotic). Derived from the child-language root сися (or титька), historically used in nursery talk for nursing or a mother’s breast, related to the verb сосать (to suck). In modern everyday speech, colloquial slang, and adult internet culture, it is a highly common, informal noun for a woman’s breast (на фотке видна сися — “you can see a boob in the photo”). It is frequently used in the plural form сиси or the augmentative сиськи.

Фигурка отличная — сиси, как на картинке. Бодрая трешка.

Smashing body: tits like on the picture. Happy C-cups.

Tits, fun-bags, breasts. Used exclusively to describe a woman’s large breasts, carrying a tone that ranges from crude admiration to comical exaggeration.

Кому нахуй нужны эти прыжки через козла, залезания на веревку и бег по кругу? Чтобы повтыкать на сисяндры одноклассниц?

Who the fuck needs all this jumping over pommel horses, climbing ropes, and running in circles? Just to stare at the tits of your classmates?

Huge tits, massive knockers, massive jugs. An expressive plural noun derived from сиськи (tits/boobs), magnified by the augmenting suffix -яри. It is used in casual street slang to comment on exceptionally large female breasts, often with a mix of awe, vulgarity, or crude humour (ты видел, какие у неё сисяри? — “did you see those massive knockers on her?”).

В коридоре была замечена мельком ещё одна — высокая, темноволосая, очень привлекательная с сисярами наружу…

In the corridor I spotted another one in passing: tall, dark haired, very attractive with her jugs showing…
