InstaWife 

A new girlfriend who instantly exhibits wifey characteristics, first taking aim at removing the shit in your apartment that she doesn't like, followed by moving her own girly shit into your apartment, and culminating in getting her own spare key so she can move in with you rent free - all without your approval or positive reinforcement.
