Sarah Palin has never been one to avoid saying horrible things. Her "reload" comment. Her "Real America" comment. But the Queen of twitter may have really stepped in it this time.
"Shuck and Jive" is a term that was originally applied to slaves talking to their masters by coming up with lies or stories in order to avoid punishment. Sarah is definitely using it in such context here, and is talking about the first black President of the United states.

Update
Nick Cannon, Nas and Affion did a video showing some of the stereotypes present in the minstrel shows around the turn of the last century. The video was called Throwback and made use of the term shuck and jive.
