Nasty

Nasty describes something very unpleasant, dirty, or offensive. It can be used for bad smells, tastes, or sights; for example, “a nasty smell” means a very bad odor. It can also describe mean or unkind behaviour, like “a nasty comment”. People sometimes say they feel nasty when they are sick. The word is used both for physical things (like food or weather) and for behaviour or feelings. For example, “He caught a nasty cold” or “She gave me a nasty look”. It always shows something negative or unpleasant.
