Lit. “it will all come out in the wash” is what people in Poland say if they are uncertain about an outcome of a decision to commit to something. They say so in order to confirm that there is no way to find out before and, in a way, calm down the others taking part in the enterprise: just move on and it will all be fine. Or: “we’ll see”.
As you may see, this is a slightly different meaning from what English or American people have in mind when using this.
Lit: “out of the asshole/from the asshole”. This colloquialism came to prominence ten or fifteen years ago and is used to denote ideas or actions that are completely out of place and useless. It is often combined with the noun “pomysł” (an idea).
Lit. “in case of a W” and this letter stands for the world “war”. You use this phrase when proposing a contingency, a solution or a plan B in case something bad and still foreseeable happens.
Lit: “a beetroot”. The metaphorical meaning has nothing to do with the vegetable. It is used to denote coarse, rude, vulgar, primitive, aggressive males and is straightforward derogatory.
Lit. “a man-orchestra”, “one-man band” which you use to refer to a person with an unlimited set of diverse talents and interests. The expression definitely contains a note of admiration and is often used upon hearing about her/his new enterprise. But it also can be meant sarcastically, to point that one person cannot be even decent at many diverse tasks.
