A brat is someone who behaves badly and expects special treatment because they think they deserve it. This usually happens with kids who throw tantrums or refuse to listen to their parents.
When we use the word "brat" to describe a child, it's often because they're being really annoying or hard to deal with. Maybe they won't stop crying no matter what you do, or maybe they insist on getting their own way even when it's not fair to others. Sometimes, adults can be brats too - think of someone who always expects everything to go their way and gets angry when things don't work out that way. The word "brat" is often used in a more playful or joking way with friends, but it can also be serious if you're talking about behavior that's really causing problems.
A child who is regarded as mischievous, unruly, spoiled, or selfish.
Example: Get that little brat away from me!
