Off-color humor is kind of like a joke that might make you laugh, but might also make other people feel uncomfortable or upset. Sometimes it uses language or talks about things that are usually considered private or gross, like body parts or bodily functions. Some off-color jokes might also make fun of certain groups of people, like different races, genders, or religions. It's important to remember that while some people might find off-color humor funny, it's not always appropriate or nice to joke about those kinds of things, and we should always try to be kind and respectful to everyone.
