You might be a scrapper if:

When you drive by a burnt up house and think about how much you could get for all of the scrap instead of are the people are ok. Same with car accidents.

When you anticipate changing the oil in your truck so you can scrap the oil filter. Same with brake parts.

You might be a scrapper if your friends ask how much something is worth in scrap then laugh.

You might be a scrapper if your GF asks if she can go scrapping with you, but can't because there is scrap all over the seat.

If you've calculated how much money you could get from scrapping your house, you might be a scrapper.
