【How-to】Where did the term jitterbug come from

Jitterbug is any form of swing dance, though it is often used as a synonym for the six-count derivative of Lindy Hop called “East Coast Swing”. It was also common to use the word to identify a kind of dancer (i.e., a swing dancer). A “jitterbug” might prefer to dance Lindy Hop, Shag, or any of the other swing dances.
