If everyone else uses the Jimmmmm's Dictionary of Mafia Terms version, there's nothing I can do about it. I just don't have a copy, so I have no way to look up the words.
Try this.
Scummy: "To make actions that scum are more likely to make. This is similar to, but distinct from, Anti-Town (hinder[ing] the Town's ability to achieve their Win Condition)."
Order received, captain.
I will just have to train myself to not use the word. I truly believe there is no way to determine if an action is more likely to be made by scum or town. (Obviously I am not referring to role powers/factional powers, etc.) If the requirement for me to call something scummy is for it to be an action that "scum are more likely to make," I don't see how I can use the word. Nor can I see how anyone can, given I find it very hard to believe anyone can prove that statement.
That definition provided also precludes one whole set of usage. It's either "That action is scummy" (describing the action as one that scum are more likely to make" OR "ashersky is scummy" (describing that ashersky is making actions that scum are more likely to make). (I am ignoring that "make action" does really "make sense" and should be take action.)
The way the definition reads to me, it appears to be saying "to be scummy" = "to make actions that scum are more likely to make" so in that sense, I think it described players, not actions.
Can we extrapolate, then, that actions taken by players who meet the above definition of scummy can also be called scummy?
Anyway, I will just have to look for another word to describe things that I find...reasontovoteable?
