The term "scamp" can have multiple meanings depending on its context.
In general, it is a slang term used to describe someone or something as untidy, disorderly or messy. For example, you might say that your room was in scamp if there were clothes and papers strewn about everywhere.
However, the word can also be used more specifically to refer to a type of sailing vessel - usually small and fast with one mast. These boats are often used for recreational purposes such as racing or day trips.
In addition, "scamp" is sometimes used in British English as a term of endearment for a young boy, similar to the American word "cutie."
