brown bag

brown bag — An informal meeting or seminar, typically held during lunch, where employees gather to learn about a specific topic from a colleague or expert.

In simple English

A brown bag session originated from the practice of employees bringing their lunch in brown paper bags and eating while attending an informal presentation. In tech workplaces, brown bags are casual, non-mandatory learning events where senior developers, product managers, or external speakers share knowledge on technical topics, best practices, or industry trends. These sessions are meant to be relaxed and encourage team learning without the formality of scheduled training. Brown bags strengthen company culture and help knowledge sharing across teams.
