First Lady Michelle Obama, Dr. Jill Biden, Andrew Barry and his family give the command for, "Gentlemen, start your engines." on behalf of 'Joining Forces' - a group that helps military families prior to the NASCAR Sprint Cup Series Ford 400 at Homestead-Miami Speedway on Nov. 20, 2011 in Homestead, Florida

*Video of America’s first African-American First Lady being booed by a predominantly-white crowd of NASCAR fans this weekend in Homestead was of course noted by Rush Limbaugh.

He went on his radio show Monday to defend the folks in the stands, saying the boos rang out because Michelle Obama has a bit of “uppity-ism.”

The black community associates the term “uppity” (usually paired with the N-word) with white racists suggesting an African-American is being presumptuous by not knowing his or her proper, lesser, place.

Secret service agents and a police officer use binoculars to scan the infield as First Lady Michelle Obama and Dr. Jill Biden attend the NASCAR Sprint Cup Series Ford 400 at Homestead-Miami Speedway on Nov. 20, 2011 in Homestead, Florida.

Limbaugh used the term while attempting to label Mrs. Obama as using taxpayer dollars to foot an extravagant lifestyle that NASCAR folks just “don’t quite understand.” His full statement:

“We don’t like paying millions of dollars for Mrs. Obama’s vacations. The NASCAR crowd doesn’t quite understand why when the husband and the wife are going to the same place, the first lady has to take her own Boeing 757 with family and kids and hangers-on four hours earlier than her husband, who will be on his 747. NASCAR people understand that’s a little bit of a waste. They understand it’s a little bit of uppity-ism.”
