It was not used in a pejorative way by either blacks or whites but as a "hip", descriptive way of identifying a person, usually a male, of the negro race, such as in the phrase "splib dude". Likewise the descriptive and non-pejorative term "chuck" was used to describe a white person, however it was also used to describe the Viet Cong (VC), such as in "Victor Charlie", "Charlie" or just "Chuck" In fact, one might get vanilla or chocolate creme filled cookies that were included in the field "C" rations. These were commonly referred to as "chuck" or "splib" cookies.
