Quoted from Beatnik-Filmstar:
Boring truth - it's just a band name. I like them and always thought it was a cool turn of phrase. Have used variations of it for logins all over the internet for years. (Then they got back together for a bit and I felt a little weird.)
Ha! I get it. I’m Krupps. I have been since the mid to late 1990s. I needed a user name for something and there was a Krupps brand coffee machine in front of me. The rest is history. 20+ years I’ve been Krupps.
