A person, usually of beastly qualities, that can perform feats of such a beastly nature, it is said to be blasphemy, or Magic.

The initials of a Beast Magician are B.M.

Anyone that says that B.M. stands for bowel movement is a person that obviously has no confidence about their social standing, so they must make jokes about different topics in the field of excrement.
Person 1: "Yo, that guy is such a Beast Magician, hey, he's a B.M.!!!!"
Person 2: "He's a bowel movement?" (Looks for approval from his friends that he is funny)
Person 1: You are an idiot.
Person 2's "friends": Yeah, you are lame.
