A sale that was not worked for. Also known as a lap-sale.
Customer walks into store with a bag of money wanting to purchase a car. The sales man just received a gaddis as he didn't have to work hard to get the sale.

The act of sucking two or more dicks at the same time
I tried to see how many dicks I could gaddis at one time, but I could only fit three.
