BM

Music: The abbreviations "BM" are known amongst metal enthusiasts as Black Metal. The same follows for it's widely unknown subgenres USBM (United States Black Metal) and NSBM (National Socialist Black Metal). Although, NSBM itself is hotly debated whether or not it belongs to the older BM idealologys. Any other abbrevations outside Black Metal's offspring are considered to be jokes.

If you think Cradle of Filth or Children of Bodom are BM.. do yourself a favor and kill yourself.
