"Let's do the Time Warp again!" Be prepared for wild and crazy and you won't have a problem. Audience participation is what has made Rocky Horror a cult classic, so just play along and go with the flow. It is beyond bawdy, so if crude language doesn't offend you (this is where the audience participation comes in), you'll be okay. If bawdy/crude language and highly suggestive movie content is not to your taste, it could be a long evening for y'all.
