The first person would post a piece of dialog, a link to a scene of the TV show or Movie
(if possible), some info about it, or a name of an actor or actress that have stared in it.
The next person then would try to guess the TV show or Movie that the first person gave a hint to. (May ask questions)
Once someone guesses the TV show or Movie, they (The first person it guess it right, after being told so) would then post the next. The game would then continue so forth.
