Juju

Juju or ju-ju () is a spiritual belief system incorporating objects, such as amulets, and spells used in religious practice in West Africa by the people of Nigeria, Benin, Togo, Ghana, and Cameroon. The term has been applied to traditional Western African religions, incorporating objects such as amulets, and spells used in spiritual practices, and blood sacrifices. This is under the belief that two vessels (most commonly a monkey's head is used) that have been in close physical contact with each other have similar spiritual properties and in turn, makes the objects possible to manipulate.

In a general sense, the term "juju" can be used to refer to magical properties dealing with luck, whether good or bad.

The name is also associated with the music genre, Jùjú as well as a slang term for the energy of something or someone. Provided by Wikipedia
