A brat is a person, typically a child, who acts in a spoiled, demanding or annoying way. Such an individual may also show tantrum, be unresponsive, or become entitled when things do not go his/her way. The term is common with children, but it may also be used in jest over adults who behave stubbornly or playfully in a jibing manner. It may be slightly offending to other close friends and family members, depending on the tone, and bring a laugh among them. Know more about brat meaning
