If you want to come around here Khalifk I will offer you the definition of a Kirkby kiss in the meantime Kaffir is defined below

Kaffir, kaffer or kafir, which once was a blanket term for black southern Africans (see Kaffir (historical usage in southern Africa)), is now utilized exclusively as an ethnic or racial slur. The original meaning of the word was 'heathen', unbeliever or infidel, from the Arabic Kafir.[1] Portuguese explorers used the term generally to describe tribes they encountered in southern Africa, probably having misunderstood its etymology from Muslim traders along the coast. European colonists subsequently continued its use.[2] Although used often inoffensively between the 16th and 19th centuries, as racial tensions increased in 20th century South Africa, its use became more racially slanderous than just a general word to describe a race of people.
