A sex act in which a roll of nickels is used as a strap-on. After the act is completed, the receiver then urinates (or defecates) the nickels out onto the back of their partner.
"My girlfriend told me to stop listening to Crazytown and come into the bedroom because she was in the mood for me to give her a nickelback immediately."
