Get the pre crack back ass fat mug.
A female whose life revolves around fucking over those she knows and doesn't even know and denies the obvious such as stealing your belongings while this loser crack back reject is wearing your very stylish clothes and in possession of your personal belongings.

This snake has no morals or conscience and lies thru the very cracked back where a real human possesses a spine.
That crack back where is wearing my clothes bc those jeans and tank top were in the RV I assume she hand a hand in stealing. She is a real snakey crack back never going to be anything solid in her life!
