Check out the new meaning of Buhari according to Wikipedia

Buharism is a Term rooted in the politics of Nigeria, referring to the economic principles and the political ideology of the military government of Nigeria headed by General Muhammadu Buhari from 31 December 1983 to 27 August 1985 when he and his deputy were removed in a palace coup for 'continuous misdirection'. This ideology shares common features with fascism; the government was a right-wing nationalist government that pursued corporatist economic programs and curtailed personal freedoms. Economic reforms were characterised as moving the political economy away from the control of a group of people the Buhari administration labelled as a "parasitic" elite, and into the control of a group of people the same administration labelled as an emerging "productive" class.
At its root, Buharism represented a return to harsh right wing military dictatorship after 4 years of civil rule in Nigeria, 1979-1983.
