When I take my car into the shop for a lube and oil change, the technician produces a long computer print-out of all of the exciting things done to my trusty steed. One of the items on this list of services is lubrication of the parts of the chassis which are supposed to move, one against the other. The technician actually notes how many places he/she squoze grease. These are recorded as "Number of zerks: __"

A zerk is a grease fitting on a machine, a sort of hollow nipple, over which a grease gun is fit, and through which grease is applied to moving parts.

It is also very cool to say aloud.
