What is "ompuff"

Belmiro Hosi (born June 29, 1980) better known by his stage name as OmPuff is an Angolan–Namibian kwaito and hip hop musician who rose to widespread fame in 2005. He is one of the liveliest performers on the Namibian local scene. OmPuff signed to Mshasho Productions in 2006. He nicknamed himself Puffy after childhood hero Puff Daddy, (now Diddy). After doing more and more kwaito Puffy eventually became OmPuff, making it sound more African. OmPuff speaks fluent Oshiwambo, Afrikaans, Portuguese, and English.
