Used in a political sense. This phrase is used towards Black Americans when other ethnic groups (usually white conservatives) feel like a black individual is perceived as a "safe negro". One whose presence doesn't "threaten" others. One that others wouldn't see as militant, conscious, or a "thug". You can find this phrase used primarily towards black conservatives, black people are often known to talk down to Black Americans, or Black Americans who simply aren't overtly stereotypical in the negative sense.
This phrase can be seen as code speak by suspected white supremacists. A racial epithet disguised as a compliment to denigrate Black Americans

I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
Short-hand for the word floccinaucinihilipilification, meaning the estimation of something as valueless (encountered mainly as an example of one of the longest words in the English language).
