Song meaning of Friesenjung by Ski Aggu, Joost & Otto Waalkes

Well, well, well, we have "Friesenjung" by Ski Aggu Joost & Otto Waalkes. Now, this song is all about being a "Friesenjung" which translates to "Frisian boy" in English. It's like they are proud of being from behind the dyke, which honestly sounds like a very questionable euphemism. They're just living the "Friesenleben" which seems to consist of Heineken, Rotwein, and Berliner Kindl while feeling like Gigi D'Agostino with "The Riddle". I mean, who doesn't feel that way, right? But wait, one of them is not even a Friesenjung, but a Berliner Kindl. Seems like he's just trying to fit in with the cool kids. They go out with Joost at night and get "mies betrunken" which sounds like a good time, but then it's dark again? Confusing stuff. And why are they talking about kissing someone's sister? That's just inappropriate. Anyways, despite not knowing where they are half the time, they're proud to be Friesenjungs and live behind the dyke. You do you, Friesenjungs, you do you.
