My is from a russian revolutionary song, that has a line: "the white army and the
Black Baron want to force on us the tzar again".I am not a tzarist, i am antikommunist, so i picked that one. Additionaly BB was the nickname of highly toxic gas, used in ww1. There are several more BB's in history and all of them naughty.
Besides, BB is cool.
