A: Was it fun at the party you went yesterday with your husband?

B: Not at all. I soon got bored with the shoptalk of the nuclear engineers, which I barely understood.

Note: First used in the late 19th century, this term refers to “talk about one’s work or occupation, especially after the workday is over.” It’s obvious that “shop” here refers to “workplace.” For example: There was a lot of shoptalk at the office party.
