In episode 3, Lindsey reveals to Raylan that she and her ex-husband stole from people and that they specifically used something called a badger game. The next weekend I watched a 1941 movie, Shadow of the Thin Man, that mentioned that one beautiful but nefarious character’s expertise was the badger con.
I had never heard of it, so I checked Wikipedia:
There are two competing explanations for the origin of the term badger game. One explanation is that the term originated in the practice of badger baiting. Another says that it derives its name from the state of Wisconsin (the Badger State), where the con allegedly either originated or was popularized.
This con has been around since at least the early 19th century. There are several variations of the con; in the most typical form an attractive woman approaches a man, preferably a lonely, married man of some financial means from out of town, and entices him to a private place with the intent of maneuvering him into a compromising position, usually involving some sort of sexual act. Afterward an accomplice presents the victim with photographs, video, or similar evidence, and threatens to expose him unless blackmail money is paid.
The woman may also claim that the sexual encounter was non-consensual and threaten the victim with a rape charge. It can also involve such things as the threat of a sexual harassment charge which may endanger the victim’s career.
If photographic evidence is not used in the scam, then an accomplice will usually burst into the room during the act, claiming to be the woman’s husband, father, older brother, etc., and demand justice. The con was particularly effective in the 19th and earlier 20th century when the social repercussions of adultery were much greater. A famous person known to have been victimized by the scheme was Alexander Hamilton, whose adulterous affair with Maria Reynolds was used by her husband to extort money and information from him.
