It may help to think of a scene as the BDSM equivalent of what might be considered a romantic interlude or erotic encounter. While what constitutes such an encounter will vary depending on the people, kink and lifestyle involved, almost everyone in the community uses the term.
A scene can take place in private between two people, or in a club where it can be viewed by an audience. When a scene takes place in public it may be because the participants enjoy the thrill of being watched by others, or because of the equipment available, or because having third parties present adds safety for play partners who have only recently met. There is an etiquette in most clubs which regulates how the onlookers may interact with the people in the scene.
The term also has another use among people into BDSM. Many refer to the general BDSM community as "The Scene."
