The Copperbottom Act 

Generally the act of using a scam method to take more than 50% off of a deal.

Trader 1: Damn it! I made a terrible trade! I lost about 50 dollars in my inventory!
Trader 2: Well...maybe the guy you traded with pulled off The Copperbottom Act on you and took advange...
Trader 1: Ugh...I think you're right...I'll be a little more cautious next time...
