Cách sử dụng
The expression "bash up" means to hit or physically attack someone or something violently. It is often used informally and can refer to either an intentional or unintentional act of violence. This phrase should be used in a casual setting with friends, rather than in a professional setting. For example, "He bashed up that bully after he insulted him at school" or "I accidentally bashed up my phone when I dropped it on the concrete."
