mall freak
A person, usually a young teenaged woman, that goes to the mall more than three or four times a week to shop and be seen by others in the latest fashionable or risque attire. Mall freaks usually carry around bags from the many department stores where they have shopped. Another feature of the Mall Freak is that when they wake up, usually an hour before the mall opens, they head straight to the mall and spend all day at the mall walking around. Mall Freaks are usually on a cell phone having multiple conversations with people as they walk from store to store. They are also known to travel in groups. 
Zeena, the mall freak, spends all of her money at the mall and then wonders where all of her money went.
