bottle is a container typically made of glass or plastic, used for storing liquids.
But in slang, bottle can mean:
1. Courage or nerve (British slang)
2. To fail to do something due to fear (British slang)
3. The act of bottling something up (suppressing emotions)
4. In sports, to lose a game from a winning position (colloquial)
bottle 最基础的意思就是瓶子，一般指玻璃瓶或者塑料瓶，用来装液体啥的。
但是老铁们注意啦，这词儿在俚语里可有意思了：
1. 表示"勇气"、"胆量"（英国俚语） - 比如"He's got no bottle"就是"这哥们儿怂得很"
2. 表示"因为害怕而放弃"（英国俚语） - "He bottled it"就是"他临阵退缩了"
3. 指"压抑情绪" - "Don't bottle up your feelings"就是"别把情绪憋心里"
4. 体育比赛中"领先情况下被翻盘"（口语） - "They totally bottled the game"就是"他们妥妥地被逆转了"
补充知识点：这词儿在英国用得特别多，尤其是足球圈儿，经常听到解说喊"XX队又bottle了"，意思就是领先被翻盘，贼扎心！
