Cách sử dụng
The word 'crud' is slang for something that is dirty, gross, or unpleasant. For example, if you see a pile of garbage on the side of the road, you could say "Ew, that's some nasty crud." It can also be used to describe something that is not working properly, such as a broken computer, by saying "This thing is just a piece of crud." However, it is important to note that 'crud' is a casual term and should not be used in formal situations.
