A term for Jibberish Diribitated from an African tribe based off a man who would appear during domestic violence ending by beating the woman who started the conflict, during the said visit he would say jibberish hence the tribe called it mumbo jumbo. So remember when someone says Mumbo jumbo be sure to report them to HR for premoting african wife beating
