Yeah, it's jokey pseudo-German, like the old 1950s hacker meme about Der Blinkenlights [0].

It's weird to people familiar with real German, since 'V' in German is pronounced like 'F' in English.

It's like they took a word already from German ("wiener" as in hot dog) and then broke it while trying to make it more German, or something.
