Diminutive of "Dudaš", which is in fact not a common term in Slovakia (NB¹: ➺ homonyms, &c.); The vocative (grammatical form) "dudašku" occurs, however, twice in Kuhač, in the text of one of the songs from "Slovačke narodne pjesme iz zbirke Ivana Kollara" (Budin, 1834 [sic]); Budin is the name of a locality in the Trnava region (NE of Bratislava), and of a mountain in the Carpathian Mountains (in the region of Žilina, near the border with Poland); NB²: The Slovak title of Kuhač's source reads, however, as follows: Jan Kollár: »Národnié zpiewanky čili pjsně swětské Slowákůw w Uhrách…« [Folk songs of the Slovaks in Hungary], vol. 2 (w Budjně [i.e. "in Budin"], 1835); NB³: On the basis of the fact that Budin is also an ancient name of Buda [i.e. the castle district of Budapest], combined with the information that the University of Trnava was relocated to that place in 1777 (➺ link to ESN below!), it is - in my perception - highly conceivable that Kollár's book was published in Hungary.
