1.
review meeting; debriefing; post-mortem
A gathering held after an event or project to look back on what happened, discuss what went wrong, and draw lessons for next time.
Compound of 反省 (reflection, self-examination) + 会 (meeting). Despite the word's literal sense, a 反省会 can be lighthearted — among friends it sometimes just means gathering for drinks to rehash an event.
