Talk shop
means to talk about work-related topics, especially in a social setting where work isn’t the main focus
Examples:
1- At the family barbecue, my uncle and his colleague couldn’t stop talking shop about the new project they’re working on.
2- My friends and I promised not to talk shop during our camping trip, but somehow, we ended up discussing office gossip around the campfire.
