filthfest 

A disgusting example of the female of our species.

Will have any kind of sex with any kind of person(or any mammal for that matter).
She usually does not wash herself well. And will surly cover her own odor with too much perfume.
She will always stalk her prey and wait until they cant stand on their own before making her move.
This is the girl that goes home with the drunkest guy at the bar and will always cause trout mouth.

"Look at that chick over there, what a nasty filthfest she is huh? Im gonna stop drinking RIGHT now."
