"Shucking and jiving" was a tactic of both survival and resistance. A slave, for instance, could say eagerly, "Oh, yes, Master," and have no real intention to obey. Or an African-American man could pretend to be working hard at a task he was ordered to do, but might put up this pretense only when under observation. Both would be instances of "doin' the old shuck 'n jive."
It has been adopted into non-Afroamerican speech, with a reference to behavior adopted in order to avoid criticism.
Jive: Trying to adopt a new social status, pretending to be "all that" + a bag of pentium chips.
as chris rock once said somewhere (I can't remember where from) "Ain't no shuckin' and jivin'"
Percy: Yeah man, niggah was shuckin' and jivin'.
