If she wasn't so huge I'd say she was a serious crackhead.
But, upon further review, I just decided to accept that she was just another wack job (there's always one on per episode it seems). I was expecting her to start speaking in tongues or something to that effect.
As a dideline, if I was the camera crew, I'd have been gone like a foreskin at the first hint of "Get out of my house" - there'd have been no telling this guy twice.
