When something or someone is not *technically* Jewish, but might as well be due to LITERALLY everything about them, including looks and mannerisms.
Like delis, George Costanza, and most hot moms under 5'8, for example.
Milo: Hey you want to do brunch this Saturday, I am macking hard on this new chick, Veronica, she will be there with friends.
Noah: Isn't she Jewish, does she go out Saturday?
Milo: Nah, she is just kosher style, she looks Jewish because she dyes her hair red, is 5'2, and still talks about her slutty semester abroad in 2004.
Noah: Cool, let's get some bacon, brosef.
