Meaning:
Lit. “on a full whore”. The “kurwa” being the most common Polish swearword, it does not necessarily mean a prostitute here, more like US American “fuck”.
Sajgon
Meaning:
Lit… “a Saigon”, ie. the old, traditional name of the largest city in Vietnam. It is invoked by Polish people to describe an extreme, usually highly unwelcome situation.
Wiązanka
Meaning:
Lit. “a wreath, flower bundle”. In Poland you normally use the word to describe a composition of flowers, twigs, ribbons you lay on a grave. But there is another, colloquial, meaning that most Poles understand well.
Dopchać się do koryta
Meaning:
Lit. “to push oneselft to the trough”. This is a commonly used metaphor for someone or a group of people managing to get elected to lucrative state or private positions. You hear it often from Polish people talking politics – no matter if on a borough or an EU-level.
Wihajster
Meaning
This strange colloquial word is used as a placeholder for an object you don’t know or don’t remember the name of. Its use is similar to the French “ce machin” or English “widget” and it also brings a comical element to your sentence: I am talking about this strange and not really important thing, I don’t even know how to call it but you know what I mean.
