過密
Meaning: Overcrowded or too active — used for an online space, server, or chat that is overwhelmingly busy.
過密 (kamitsu) is the opposite of 過疎 (kaso). It originally means overpopulation or overcrowding and is used in internet slang to describe online spaces that are too active — servers crashing from too many users, chat scrolling too fast to read, or games with login queues. While being popular is positive, 過密 implies the activity has become a problem. In gaming, 過密サーバー (kamitsu sābā, overcrowded server) means lag and wait times. The term pairs naturally with 過疎 as two extremes of online community health.
Examples
- リリース直後で過密すぎてサーバー落ちた。 刚上线的时候人太多,服务器直接崩了。Justo después del lanzamiento estaba tan saturado que el servidor se cayó.출시 직후라 너무 과밀해서 서버가 터졌어.
- チャット過密でコメント全然読めないじゃん。 聊天刷得太快,评论完全看不过来啊。El chat va tan rápido que no se puede leer nada.채팅이 과밀해서 댓글을 전혀 못 읽겠어.
- 過密鯖は避けて過疎鯖で始めた方がいいよ。 别去人多的服那个服,去人少的服开始比较好哦。Es mejor evitar los servidores saturados y empezar en uno tranquilo.과밀 서버는 피하고 한산한 서버에서 시작하는 게 좋아.
