I don't know squat about Serbian, but with the help of other Slavic languages, I think it means literally: Come, yours are legs younger. The adjective seems to be after the noun, which is unusual for most parts in Slavic languages, except Polish, which uses it extensively, as was discussed here, and Czech, which has (rarely) that order in some fixed expressions. Ústav pro jazyk český is an example that comes to mind. Is my interpretation correct? What other Slavic languages place adjectives after nouns? I'm not talking about the predicate position, because in that position adjectives are typically separated from nouns/pronouns by a linking verb. I'm interested in the attributive position.
