A pop punk girl is someone that acts 13 years old, obsesses over pizza, tumblr, and boys. They constantly express how badly they want to make out with boys and how lonely they are. Oh yeah, they also enjoy angsty pop punk music. And never stop using the word "angsty"
Its like girl pop but better, more emphasis on someone who is a girl pop. If you are girl poppier you are the ultimate girl pop and should be honoured. It is a real legitimate word.
