sosi pisos, which came from Russian language (rus.: соси писос), means "suck a dick": sosi - is a transliteration of the corresponding Russian word that is
translated as "suck", and pisos - is a non-dictionary word which was coined by kids by transforming another Russian word "писюн" which could be translared in English as "prick", "pecker" or "penis".
Expression sosi pisos became very popular as a meme. It is usually printed on a picture of a grey stripped cat that has laid its paws at the wooden crossbow which is a piece of some kind of a house furniture, possibly a locker or table. Print "соси писос, мем" in Google and you will find at once a picture of that cat. Sometimes the original inscription "соси писос" at the cat's picture is replaced with "ты знаешь, что делать", that is
translated as "
you know what to do", that of course mean "suck a dick".
In a publick chat someone gives a picture of a "sosi pisos" cat with the inscription:
"Guys, look after a cat. I will come soon." Then those
participant leaves the chat. This means that
the person think the topic of the
conversation is meaningless, and chat participants are assholes.
