SDMF is a the creation of Black Label Society--a band led by Ozzy Ozborne's guitarist Zakk Wylde. SDMF is a unique hybrid of shared ideals and fan club. The actual acronym is most commonly read out as either "Society Dwelling Mother Fucker" or "Strength Determination Merciless Forever"

I am a SDMF, and do not wear pink polo shirts with the collars up.

Stupid Drunk Mother F**ker

"you SDMF!!" - play on words of the popular slogan of Zakk Wyldes Black Label Society - turned against Zakk following being too drunk to play whilst on tour a few years ago.
