The following passage from Planescape: Torment is when Ghysis the Crooked is describing the different demons that humans may make contracts with. What is the meaning of the word "peel" here? It seems like it could be a euphemism for "flay", but I feel like it's not meant that way here.

> The man nods. "They don't usually pay as much as th' tanar'ri, but
>  they don't break their written word. They're smart, though - several
>  hundred, hundred, *hundred* fold smarter an' they been makin'
>  contracts since time began. They know 'ow ta peel someone with words,
>  they do. Sign, an' most likely ye'll be peeled an' hung ta dry in
>  their legions..."

I tried checking Wiktionary and Oxford but didn't see any definition that fit. The slang from this game is based on old English slang and rhyming slang, neither of which I am familiar with. So it may likely be an obscure use not listed in most dictionaries.

Edit:
The same character also has the following dialogue containing the same usage of "peel":

> 
> "Chances are when ye sign up, they peel ye so yer tour o' duty is 'til
>  time itself grinds ta a 'alt. Even death wouldn't be a release, 'cause
>  then ye sink inta th' Lower Planes an' get dredged back up as
>  somethin' worse'n ye were before. Then they got their talons on ye fer
>  all eternity."
