nigger fuckery
As is for "buggery" (the homosexual act of sodomizing a little boy) the act of nigger fuckery is indeed the act of intercourse with a nigger, whether heterosexual or homosexual in nature. Persons of breeding and taste may sometimes engage in sexual relations with the lower classes, such as in the case of Thomas Jefferson having private (yet indiscreet) relations with negro staff.
Thomas Jefferson's relations with Sally Hemings produced several mulato offspring. Surely this is a blatant example of nigger fuckery occurring at Monticello.
