意味

An offline meetup where people who know each other from the internet meet face-to-face for the first time.

オフ会 (literally 'offline meeting') describes gatherings of people who originally connected through online communities, forums, or social media. These meetups are a long-standing tradition in Japanese internet culture, dating back to 2channel and nifty-serve era. オフ会 can range from small groups of two or three to large organized events with dozens of participants. While generally positive social events, safety concerns (meeting strangers) are often discussed, especially for younger participants.
