During the meeting, the team used a lot of shoptalk that was hard for outsiders to understand.
Shoptalk is formed from "shop" (from Old English *sceoppa*, meaning a place of business or trade) and "talk" (from Old English *tale*, meaning speech or conversation). The term refers to conversation or discussion that is specific to a particular trade or profession, typically occurring in a business setting.
Think of a 'shop' where people are discussing their 'talk' about work-related topics — that's what shoptalk means.
