A girl dressing in slutty clothes, wearing an exessive amount of make-up; A mess;Trying too hard; Looking like a whore.
That girl is so scrapped out!
When you go from being able to afford food and healthcare to being broke and miserable, and being cut off from any kind of help. Not mutually exclusive with homelessness but usually happens at the same time. A scrapped out person is poor and starving, living on scraps.
Or when a person scraps out for good, they finally kick the bucket (if they have one) from lack of access to medical care or resources, or from poisoning due to poor quality of living conditions.
Person 1: Hey did you hear Jimmy scrapped out yesterday? It was real tragic.
Person 2: No, I didn't hear anything because I can't afford to fix my hearing aid, which I need because I'm stuck working below-table construction jobs where they don't give you earplugs for the loud mechanical screeching you're always within ear-drum-bursting proximity to.
Person 1: Damn, sounds like you're about to scrap out too.
