Thieves' Cant 

As per Wikipedia: Thieves' cant (also known as thieves' argot, rogues' cant, or peddler's French)1 is a cant, cryptolect, or argot which was formerly used by thieves, beggars, and hustlers of various kinds in Great Britain and to a lesser extent in other English-speaking countries. It is now mostly obsolete and used in literature and fantasy role-playing, although individual terms continue to be used in the criminal subcultures of Britain and the United States.

It was commonly believed that cant developed from Romany. Etymological research now suggests a substantial correlation between Romany words and cant, and equivalents, in many European languages. However, in England, Scotland, and Wales this does not apply. The Egyptians, as they were known, were a separate group from the standard vagabonds, and cant was fully developed within 50 years of their first arrival in England. Comparison of Romany words in the Winchester Confessions taken in 1616 with modern Welsh Romani show high commonality. This record also distinguished between Romany and Cant words and again the attributions of the words to the different categories is consistent with later records.

Me personally, i think it means YEE HAW PARTNER YEE HAVE YAWS YEE LAST YAAAAA!!!!

Criminal 1: “Ho sir, you’re clearly a f'reign'r. Wend readeth this cant so yond thee may knoweth how to maketh wage 'round h're”

Wandering Beggar: “what?”

Thieves' Can't 

A cryptolect, an argot, and/or a set of secretive low-key code word terminologies (also known as thieves' argot, rogues' cant, or peddler's French) used by thieves, beggars, vagabonds, criminals and hustlers in primarily of Great Britain in the early 16th century onwards until falling completely out of use in all language and literature by the late Victorian Era.

Simply put, it was the speakeasy, lowkey language and/or code word in itself, at the time used to avoid tipping off less knowledgeable agents of law enforcement.

The term was likely devised by the self declared "King of the Gypsies of Derbyshire's Devil's Arse", now known Peak Cavern, by either at the time Richard Skelton and/or/both his soon to be successor Cock Lorel (his real name a mystery, lost to time, but his pseudonym meaning rascal leader) and their band of misfits who either preyed upon the rich or all folk of the Shires of Britain at the time.

The term became extremely popular after literature of the 16 and mostly 17th centuries would depict the lives, both fictional and real, of these rogues, both recent and historic at the time, by modernfolk who could read to those who could not, usually at less reputable pubs or "public houses"at the time.

In modern times, it's used primarily by geeks who play tabletop RPGs or those who have a keen interest in histoical literature. Some secretive clever groups of our society today might adopt the code for their own use in secretive deeds.

Thief A: "oi good fortune, brethren. Spot a pint for a recount of my most recent misfor-?"

Thief B: "nay, AN' HUSH! ...now see gent yonder table there in the nook? Dressed fine, he is, aye? Alone? Surly well endowed in coin an no match us? Thieves' can't."

Thief A: "Behind the pub when he goes to take the piss? We can purloin the loot and disperse, if you can muster up that pint fo'a fellow roué?"
