Cách sử dụng
The expression "a bad lot" refers to a group of people or things that are considered undesirable or problematic. For example, if someone says "those kids are a bad lot," they mean that they think those kids are troublemakers. It can also be used to describe a single person who is seen as being morally corrupt or unpleasant. It's not a very positive expression, so it's important to be cautious about using it in polite conversation.
