Slang for lively, energetic, or fun; ready to dance or have a good time; also means to move with quick, jerky motions.
From 'jig,' a lively folk dance, plus '-y' suffix. 'Jig' itself came from French 'gigue' in the 1500s. The slang sense 'with it, lively' developed in the 1800s, popularized in hip-hop and rap music in the 1990s.
Will Smith made 'jiggy' iconic with his 1997 hit 'Gettin' Jiggy wit It,' but the word has roots way deeper in hip-hop and African American Vernacular English. That one song probably taught more people the word than centuries of folk dancing could have!
