hup / hep / hip: These words have existed since at least the turn of the last century. 'Hup' originally referred to the cadance of a marching band, i.e., hup, two, three, four. Thus associated with music, it became 'hep' during the swing era, when it became 'cool' to use it to refer to happenin' dudes and dudettes. In the 60s, when it became 'hip' to be cool, the beatniks popularized the term.
