<P> Audience participation also includes dancing the Time Warp along with the film, and throwing toast, water, toilet paper, hot dogs, and rice at appropriate points in the movie . Many theatres forbid throwing items that are difficult to clean up . In many cases, a total ban on throwing objects has been instituted due to severe damage to movie screens . Fans often attend shows in costume as the characters . At a now - defunct theater in New Orleans, the local "Eddie" would ride his motorcycle down the aisle during Meat Loaf's / Eddie's song, "Hot Patootie ." On the West Coast (Northern California, Mountain View to be specific) newcomers to the midnight showings were called "virgins" that must be "deflowered" as they watched the showing and saw the audience participation . For the rain scene, umbrellas were opened . A toast had the audience throw toast in front of the screen and similar other items were displayed by the much more liberal audience . </P> <P> During a showing of Rocky Horror, ad lib responses, more commonly known as call backs, are lines the audience may shout out in response to events occurring on screen, as a form of audience participation . In some venues, audience members who provide incorrect or poorly timed responses may find themselves angrily shouted down just as if they were being disruptive in a normal movie . However, creative new lines are usually applauded and even added to the local repertoire . There have been audience participation albums recorded and scripts published . However, most fans feel that it is preferable for responses to grow organically from the local culture . </P>

When did rocky horror became a cult classic
