Copper fighter

This can have 2 meanings. One is a synonym of penny pincher; a word for an extreme cheapskate who is very stingy. They are a copper fighter because they haggle you down to a cheaper price, or they'll grumble about something reasonably priced being "unfair." Also because pennies have a copper coating.

The other meaning is someone who steals copper material such as wiring, roof panels, or copper pipes to exchange for money at a salvage yard. Usually they commit this theft to support a drug habit. They're copper fighters because they'll do whatever it takes to support their drug addictions, meaning they'll fight tooth and nail to get the money in the form of the copper.

That copper fighter really tried to bring the price from 200 down to 60. This is a supermarket chain not an auction house!

I caught those 2 copper fighters trying to steal my Christmas lights again! Sent them running for the hills!
