What does it mean to tell fortune with a broom?

I'm going to do horoscope today and say I have an iron broom. What does an iron broom mean?

Hahaha! It's called an iron broom. Brooms sweep things, including garbage and dust. If the criminal iron broom, regardless of gender, specializes in sweeping each other. Sweep away all the money and things. Ha ha! That's great. But how do we know whether we are guilty or not? Where is the broom? Male life, born in Shennian, committed iron broom in the first month. By analogy, people born in ugly years see the moon in September, the year of Yin Wu in September and the year of Mao Yue Hai Mao in February, all of which are iron brooms. Female life, Shen sees ugly December, has been ugly November, September, and August are iron brooms. But don't be afraid, these are all bluffing!
