Wow, what and extremely good idea (and useful idea!) for a thread!
Well there are related bits of Brokie vocab that seem essential around these parts and most of them involve acronyms, etc.
STS- the Story to Screenplay book
TOB- the Old Board (usually referring to the "Big Board" on imdb or sometimes "PT" on imdb). Can also mean the Old Board
sBig Board/ TOB- the main message board for the film Brokeback Mountain on imdb
PT/ TOB- "Pierre Tremblay" board on imdb named for one of the First Assistant Directors of BBM and was a smaller message board on imdb dedicated to Brokeback. Like people from the Big Board, a mass exodus occured to this haven called BetterMost during the troll wars which happened in March and April... and are on-going back on the Old Boards.
BBM- is of course, Brokeback Mountain
