To offer an in-kind service to an individual while knowing full well that they are not going to accept. In return, the individual now owes you +1 due to the empty offer you had made. You also score brownie points and karma points with said individual.

The key to a successful Jewish favor is knowing the answer you will receive before asking the question.
"Ah man, I wish I had enough money to buy these panties for my gf" - Individual 1
"I don't mind buying them for you" - Not so friend Joe
"Nah, it's okay man, thanks though" - Individual 1

Not so friend Joe just scored some brownie points with Individual 1. Individual 1 now owes Joe +1.
Not so friend Joe just gave Matt the jewish favor.
