"Nine ether" is a Nuwaubian phrase used to describe very curly, wool-like hair. This type of hair is sometimes called kinky or nappy. The phrase "9 ether" was invented by Malachi York in 1990.
The Nuwaubian movement is a quasi-religious organization. It teaches about the existence of a supreme race, the Ether 9 beings, who were green. African Americans are said to be descended from the Ether 9 beings, according to this religion. Malachi York, whose original name was Dwight York, is the leader of the Nuwaubian movement. Dwight York is currently serving a 135-year prison term for child molestation.
