look up any word, like sparkle pony:
 
1.
a goodwill handshake is a handjob that is a more polite, or out of the goodness of your heart kinda sex act than, say, jerking off your boyfriend in the shower.

to be performed quietly in the backseat of a car, in a closet, or basement setting, the goodwill handshake can also be used as a way to say 'thank you' or 'good job'.
For our top 15 customers we offered goodwill handshakes in the basement as a way of showing our appreciation for the support of our cafe.
