KMFDM

Kein Mitleid fur die Mehrheit or something like that. They say it in Megalomaniac. Also, in Light, they say "Keiner macht fur dich mehr" which has a somewhat similar meaning, but I do not believe that's what they stood for.

Or, for shits and giggles, you could just say it stood for Kylie Minogue Fans Don't Masturbate.

I used to love KMFDM, but I haven't liked anything they've made since Adios, and that was like 7 years ago. En Esch and Gunter were irreplacable, and since they've left, the band has gone to shit.
