Sexual act performed by inserting a potato into an orifice (generally a vagina) and twisting your wrist as though you were checking the time on a watch.

Potato used in place of a dildo.

This act typically follows or accompanies copious amounts of drinking, usually whiskey or beer but also mixed drinks - such as Irish carbombs.
I met this kinky chick at the bar and went back to her place, where I gave her an Irish wristwatch.
