When someone has a sense of humor, it means that they are funny and can make other people laugh or smile. Having a good sense of humor is often considered to be extremely attractive because it makes the other person more comfortable and relaxed around you. For example, if you have a sense of humor, you might have the ability to make a joke to make a situation less awkward or add a playful lightheartedness to any conversation. In the case of a “chick,” a female person, having a sense of humor is often even more attractive because it implies that she is confident and not afraid to show her own personality.
