Jack is a dance style started in ‘The Music Box’ Chicago when DJ Ron Hardy was playing early house and experimental electronica. The ‘Jackin’ is rhythmicaly jacking the whole body backwards and forwards to the music.
Who's Jack? The origin of the name Jack is Old English. It is a medieval diminutive, originally Jackin (earlier Jankin), of the Hebrew name John which means "God is gracious". Alternatively the origin may also be the name Jacques which is the French form of the Hebrew name Jacob which means "he who supplants". Whatever its origin, the name and also the word "jack" were long used as a term to refer to any man, especially of the common classes.
The name Jack is unique in the English language for the frequency of its use as a verb and a noun for many common objects and actions; and also its use in many compound words and phrases. Jack was yesterday, today it's Jackathon, jackknife, jackpot, jack tar, hijack, union jack, jack straw, apple jack, lumberjack, jackhammer, jackdaw, jack o'lantern, jack-in-the-box, jack of clubs, ... as in Lord Teach Me House.
