Debtor's Prison Slang

I though this post by CJCairns at History on the Web was interesting because the slang made no sense to me.

Here's a sample:

17^th and 18^th Criminal Slang.

'Buttock & file': Pickpocket-whore.

'Rats': Public nuisances, i.e drunks, street walkers and stray children.

'Milkens': Burglars.

'Autem Divers': Church pickpockets.

'Rufflers': Strong arm men.

'Adam Tilers': Look outs.

'Stags': Informers.

'Sneaking Budges': Sneak thieves.

'Faytors': Forgers of documents.

'Vulcans': Picklock experts.

'Rattling Lay': Stealing from coaches.

I suppose I lack the cultural context for Stags and Adam Tilers to make sense. Enjoy.
