 v.— «Fliers announcing this month’s Evanston Township High School homecoming dance carry the warning: “salacious or inappropriate dancing”—often called “juking”—is outlawed. Dance tickets at Naperville North High are even more specific: “sexually explicit” and “front-to-back dancing will not be permitted.”…Spotting dancers who cross the line can be especially difficult in schools where hundreds of kids pack a dance floor and gravitate into clumps, sometimes even encircling jukers and protecting them from ready view.» —“No ‘juking’: Schools fight ‘sex’ dance” by Rosalind Rossi Sun-Times (Chicago, Illinois) Sept. 16, 2007.
