Worldwound Slang

[Anorak]

Is there any slang specific to the Worldwound like there is for the Darklands or Kaer Maga? I was thinking of adapting Planescape.

In The Worldwound Gambit, Rip and Gaffle mean a plan to con someone.

I can imagine: "That's so Abyssal!" would be a pretty big slur on an event and "Abyss take you!" would be a frequent curse.
"Now that's a succubus in disguise" could be a droll way of saying that something looks too good to be true.
"Heaven help me" and "Oh Iomedae!" could be frequent pleas when people say something stupid or irritating.

When I was at a PFS event for the 'Siege of the Diamond City' my character shouted out 'By the mammoth's t#~!!' Not sure why, but soon several other folks were shouting things out as well. Funniest one I heard was 'By the radiant breast of Iomedae... I mean breastplate!'

[Sarah Brogan]

"A snowballs chance in the Abyss."
"When the Abyss freezes over."
"A cold day in the Abyss."

All of which I'm just changing 'Hell' to 'The Abyss' from real world sayings.

Still, as for actually slang words rather than phrases... rip and gaffle have already been mentioned as both meaning to scam someone or a confidence trick (a con).

It might be worth combing through The Worldwound Gambit to look for other slang or phrases used. Due to the nature of the book (an adventuring group who are a bit on the Chaotic side) there's bound to be more, even if they aren't entirely new words like the above two.

Could also have stuff focused on mutilation like "Gore it!" or even Abyssal words themselves might be used since Celestial words don't have enough oomph and because even though its unwise to use Abyssal in a justifiably paranoid land, well, that would also be the draw for using it for swears.

Blasphemy might also be popular, "I-oh-my" as a short form for Iomedae, a part-sword-draw-part-masturbatory gesture performed just to the right of the hip where a sword would be sheathed to indicate the arrogant self-love some folks always accuse paladins of having anyway, stuff like that.

"Just yanking my Longsword, gov"
or
"Quite yanking my long sword"
