FOX Nation host Abby Hornacek takes a closer look at the topics and buzz words you find your friends and coworkers using to sound intelligent. Each week Abby and her expert guests will tackle topics we take for granted and help to explain the roots and meanings behind them.

This week, Herbert G. Ruffin, Department Chair of African American Studies at Syracuse University, joins Abby in the classroom to help with her lesson plan. Professor Ruffin explains the history of Juneteenth, how the holiday was honored by early freedmen, and how the celebration of this date has evolved through United States history.
