The term 'cult' is tricky to define, since most of these organizations can also be deemed as religions. Therefore, cults are best understood when one takes into account the context in which they were founded and the driving force behind them.

Most cults tend to be slightly weird--usually unwelcome in normal society. They consist of groups of people who adhere to the rules prescribed by the cult alone. Often, these cults are led by charismatic leaders who are nothing short of psychopaths. With that in mind, here are some of the world's weirdest cults.
