BG Bad guy.

Breaking StrategyA strategy that implements bugs in the game setup or is otherwise "unfair", usually tilting the odds of victory severely in one direction.
C9 Hexadecimal shorthand for a series of setups.
After some initial newbie games on MafiaScum, breaking strategies were quickly found for such a small game with fixed and known roles- for such a small open setup. As a result a semi-open setup was designed, now known collectively as C9, where the game is just stated to be a C9 game and the setup is one of the following:
1 Cop, 1 Doc, 2 Mafia, 3 Townies;
1 Cop, 2 Mafia, 4 Townies
1 Doc, 2 Mafia, 4 Townies
2 Mafia, 5 Townies
Hence;
COP DOCTOR
1 1
1 0
0 1
0 0
Or the number sequence 11100100, which shortens to C9.
CA / CaliforniaSetup shorthand.
A 7-man setup consisting of only one power role, a Sane cop, amidst 2 goons and 4 townies. Named CA on a similar logic from C9, and nicknamed California Mafia.
Closed SetupA game in which the roles present are not known to the players. See Open Setup.
DethyShort for Dethwing Classic.
A five-man setup which consists of one Paranoid Cop, one Insane Cop, one Naive Cop, one Sane Cop, and one Mafia.

WIFOMWine In Front of Me.
"Now, where is the poison? The battle of wits has begun. It ends when you decide and we both drink, and find out who is right, and who is dead."
"But it's so simple! All I have to do is divine from what I know of you. Are you the sort of man who would put the poison into his own goblet, or his enemy's? Now, a clever man would put the poison into his own goblet, because he would know that only a great fool would reach for what he was given. I'm not a great fool, so I can clearly not choose the wine in front of you. But you must have known I was not a great fool; you would have counted on it, so I can clearly not choose the wine in front of me."- The Princess Bride
So goes the scene from the movie that the term is lifted from. Used to cite circular logic, reverse-reverse psychology. Click HERE for a game theory analysis on the MafiaScum wiki.
