A Wall Girl is typically a 13-18 year old girl from Wall, New Jersey. They dress, act, and look like sluts, and are bitches. Characteristics include heavy eye makeup, knock off Victoria's Secret leggings, short tan Uggs, and weirdly straight hair. Since they don't live in a beach town, their moms drop them off in Manasquan, where they get wasted, and then sober up before calling their moms to pick them up. Horny guys worship them, all girls hate them, and the love themselves.
