A Jewlock is a crossbreed between a Jew and a Pollock.
A Jewish man and a Polish woman have a Jewlock for a son.
Braided sideburns that are twisted and ugly like the people that invented them. Or a Decorative ornamant you hang on your front door in the shape of a swastica or Hitler figure that wards off those dirty unwanted ones...
Christine had Jewlocks the other day.
