2.
Something improperly fixed, often mechanical or electronic. It is a derogatory term derived from "jerry-rigged" which came into use from the confusion of "jury-rigged," a nautical term for a makeshift replacement of rig that has been damaged or lost overboard, and "Gerry-built," which referred to the low quality of German manufactures in the latter part of the 19th century. Also known euphemistically as "Afro-Engineering" or "Colored Engineering"
all black people in the world, no matter where from, have always nigger-rigged their cars

3.
To build or fashion something in such a way that it works well enough, but is lacking in nice touches of desgin, or complex function. Usually built or rigged rather quickly with whatever materials and tools are at hand. Sometimes built or rigged without the intention that it last for a long time. Built to serve the needs of the moment. Built using common sense, rather than detailed instructions or diagrams. Often as a result of a very limited budget.
A term not now approved for use in polite society. If not, would you then say "N-word-rigged"? A close and acceptable synonym might be "jury-rigged".
I prefer not the use the term in print.
