Afro engineering
（重定向自Nigger rig）
Afro engineering (short for African engineering) or nigger rigging are pejorative terms for shoddy, second-rate workmanship, with what materials happen to be available. The terms may also convey a quick, temporary fix that is done technically improperly. They can also be used as verbs to describe the act of doing such work. "Nigger-rigging" originated in the 1950s; the term was euphemized as "afro engineering" in the 1970s. The terms have been used in the auto mechanic industry to describe quick makeshift repairs.
