[Cirque du So-What]

A garnishment is a means of collecting a monetary judgment against a defendant by ordering a third party (the garnishee) to pay money, otherwise owed to the defendant, directly to the plaintiff.

The weight of evidence comes down on the side of calling the act 'garnish' and the person whose wages are tapped the 'garnishee.' I consider it improper form to refer to someone's wages getting 'garnisheed.'
