A girl born into a rich family. I know no one cares about school, but I will just say, there parents can afford to send them to private school. So they will tend to be snobby. Some are in US but most are in the UK. Its pretty much imposable to get rich enough to make your kids them, but don't have kids they: suck, smell, annoy and don't do anything good anyway.
Posh girls are any girls born into money.
Get the Posh girls mug.
