but dude is not “Junge”? the accurate translation for dude would be “Mann”, “Kumpel” or “Alter”
That very much depends on your personal vernacular/dialect. Google Translate or other dictionaries adhering to Standard German might say differently, but you, as someone who apparently spent a lot of time studying the intricacies of language and the art of translation, probably also know that a language Standard does not necessarily reflect the complex realities of language use in the population.
Also, it’s a joke.
Also: Junge. Chill.
