How was it like for the dancers in the roaring 20s give examples 

The roaring ’20s dances were wild and carefree. Previously, ballroom dancing, although silly with “animal dances,” was structured and tame compared to the independent “Charleston,” “Black Bottom,” and “Shimmy” dances that took over dance floors in the roaring ’20s. Ballroom dancing continued with older and more conservative folks well into the ’30s. The new dance crazes were for the new women and men who valued extreme sports, frivolity and looser morals. Most dancing took place in nightclubs and community centers. The latter promoted marathon dancing, which at first was about who was the best dancer and later became about who could last the longest on the dance floor (not necessarily dancing, but upright). Marathon records were broken over and over again across the country: 7 hours, 20 hours, 3 days, a week. If you didn’t win the marathon, you could at least bet on the winner and thus be a winner yourself.
