teenybopper
A mother who tends to dress the exact same way as her teenage daughter. She uses the same language as her daughter, hangs at the mall with her daughter, dies her hair non-natural colors like her daughter. A teenybobber may also partake in girlish crushes on highschool boys and resort to text messages as their source of communication with the outside world.
