It is nothing more than a derogatory term used from the time Africans became slaves through the civil rights movement. The black race was purer and their skin much darker then and people who were afraid of them called them "jigaboos" because their eyes and teeth were so white and features much larger. They considered them the boogie man. This term should never be used as we have come so far as a people and it is horrible and ugly. It also has nothing to do with some of the definitions here, like people who listen to rap and hip hop music.
A fishing lure used by blacks to catch their favorite kinds of fish; ie: carp, drum, alligator gar, etc. Entirely used by blacks, since the white man does not like to use this word unless they are referring to blacks in general.
Hey Luther you got any jigaboos in your tackle box. Damn these jigaboos sure make the best lures to use for fishing. Hey nigga what color jigaboos are you using right now??
