It can also refer to the act of holding such a session. 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. ## When you hear it Our frontend team is hosting a brown bag next Thursday on React performance optimization. ## Examples - **in a team message:** "Hey everyone, there is a brown bag tomorrow at noon covering Docker best practices." - **in a calendar invite:** "Please join our brown bag session on Kubernetes scaling strategies." - **in a meeting:** "We should brown bag the incident response procedures so everyone understands the workflow." ## What native speakers say - "We're hosting a brown bag on microservices architecture" - "Join us for a brown bag lunch this Friday" - "Can you brown bag the new deployment process for the team?" ## Common mistakes - ✗ "We need to brown bag the customer about the delay." → ✓ "We need to inform the customer about the delay." (Brown bag refers to informal learning sessions, not communicating with customers. Use it only for internal team learning.) - ✗ "I will brown bag this issue under the table." → ✓ "I will discuss this issue in our next standup." (Brown bag does not mean to hide or conceal. It means to present or teach informally.) - ✗ "Can you brown bag me the documentation?" → ✓ "Can you present the documentation in a brown bag session?" (Brown bag is primarily a noun referring to the session itself, not a verb meaning to send materials.) ## Be careful Do not confuse with actual brown paper bags. The term refers to informal lunch-and-learn sessions, not physical bags. Also avoid using it to mean hiding or concealing something. ## Word forms | Part of speech | Word | Example | | --- | --- | --- | | noun | brown bag | The brown bag on API design was very helpful. | | verb | brown bag | Sarah will brown bag the new testing framework next month. | | noun (gerund) | brown bagging | Brown bagging has become a key part of our learning culture. | ## Collocations - **host a brown bag**: Used when you organize and conduct the session - **attend a brown bag**: Used when you participate in a brown bag session - **brown bag lunch**: Emphasizes the meal component of the informal session - **brown bag session**: Common way to refer to the event formally ## Synonyms - **lunch and learn**: Identical meaning; more explicit that it combines eating and learning - **knowledge share**: More formal; broader term for sharing expertise, not necessarily during lunch - **tech talk**: Similar informal presentation but does not necessarily involve lunch ## Opposites - formal training - mandatory workshop ## Practice This lesson has 4 practice exercises with instant feedback on the page: https://app.speaktechenglish.com/learn/brown-bag ## FAQ ### What does brown bag mean in tech companies?
