black, black no trade back

Following an action or the transfer of an object from one party to another, vocalizing, "black, black no trade back" prevents the receiving party from returning the action or object to its originator.

After giving Quin a paper ball, his father says, "black, black no trade back", leaving Quin stuck with the object. He must keep or dispose of the ball without returning it to his father.

TradeBack 

TradeBack is a commonly used term to describe 'cashback' loyalty schemes used in Financial markets such as: Spread Betting, CFD trading and FOREX trading.

The concept is based on the 'stake x spread/margin' for each trade, and a rebate (usually between 5% & 15%) is paid to the customer one month in arrears.

E.G. Stake (£2/pip) x Spread (5 pips) = £10 bet. On a 10% tradeback deal = £1 cashback or tradeback goes to the customer.

Tradeback 

Anytime somebody makes a trade they have qualms about they tend to do a tradeback in which they get back what they'd initially traded.

"I don't want these cards anymore, let's tradeback."
"Fucking noob."
