バグ

• 読み: バグ
• ローマ字: bagu
• 発音: /ba.gu/

意味

Bug — a software error, glitch, or unexpected behaviour in an app, game, or system.

Borrowed from English 'bug,' バグ has been part of Japanese tech vocabulary for decades. In gaming culture, バグ can refer to both frustrating errors and entertaining glitches that players deliberately exploit (バグ技). The term has also expanded metaphorically — people call any strange or unexpected real-life occurrence a バグ, as in 現実のバグ (a bug in reality) or 天気のバグ (a bug in the weather).

例文

1. アプデしたらバグだらけでまともに使えない。
2. このゲームのバグ面白すぎて逆に楽しい。
3. 今日暑すぎない？天気のバグでしょ。
