What does 'Smyk' really mean?
Well, some translate it as 'mischievious boy' or 'rascal' - and quite right so. From the image below you can get an idea what native (Polish) speakers understand under this noun. I scanned it from a Polish carrots, orange and apple juice box. Incidentally, the juice itself suits very well your body's demand on longer flights, bringing to water-acid-alcalic balance (no intention to make advertisements here).
