Murderous

Murderous wasn't her name but it described her well.

I saw Murderous clearly
She was huffing and puffing as she limped down the sidewalk
        her uneven legs trying to balance her girth
She turned and began to shout at some poor man passing by
        he made the mistake of giving her a dubious look as she approached
I saw her pull a rocket launcher of the fire and forget catagory from nowhere
        In broad daylight she fired the weapon
I heard her scream "Don't talk about me fat!!"
        Spit flew as she she stuttered and lisped
And I felt terrified that she got away with it.
