Top definition
A Polish person who denies his/her polish origins.
The word is driven from "Gefilte-fish". A meal consisting of hideous Fish patties, cooked in their own slimy gel, that Jewish Poles used to, and still are eating, today.
Yuval: Quit denying your Polishness.
Johnny: I am not Polish.
Yuval: You GEFFY, you should embrace your polishness.
