Magun is a Yoruba word in Nigeria. It is a s-xual magical charm.

Magun is used to set a trap for a cheating woman. An item is spread or spraayed on the floor; once she crosses over it and sleeps with another man besides her husband, the man will die.

Some even say Maguni is a s-xual laughing magical charm. The adulterous man will begin to laugh from on top of the woman, and die laughing.
