Goy said to be the same as gentile
Dos ken nor a goy - Something only a goy would do or is capable of doing.
A goy blabt a goy - "A goy stays a goy," or, less literally, according to Rosten, "What did you expect? Once an anti-Semite always an anti-Semite."
Goyisher kopf - "Gentile head," someone who doesn't think ahead, an idiot.
Goyishe naches - Pleasures or pursuits only a gentile would enjoy.
A goy! - Exclamation of exasperation used "when endurance is exhausted, kindliness depleted, the effort to understand useless".Several authors have opined on whether the word is derogatory. Dan Friedman, executive director of The Forward in "What 'Goy' Means, And Why I Keep Using It" writes that it can be used as an insult but that the word is not offensive. He compares it to the word "foreigners" which Americans can use dismissively but which isn't a derogatory word. Similarly, Jews for Racial and Economic Justice (JFREJ) has stated that "goy" is "Not an insult, just kinda sounds like it."Rebecca Einstein Schorr argues that the word has an established pejorative overtone. She refers to the observation "the goyishe groomsmen were all drunk and bawdy; of course, you’d never see that at a Jewish wedding" and "goyishe kop" where the word is used in a pejorative sense. She admits that the word can have non-pejorative uses, such as "goyishe restaurant" - one that doesn't serve kosher food - but contends that the word is "neutral, at best, and extremely offensive, at worst." Andrew Silow Carroll writes:
But the word "goy" has too much historical and linguistic baggage to be used as casually as "non-Jew" or "gentile." It starts with the obvious slurs – like "goyishe kopf," or gentile brains, which suggests (generously) a dullard, or "shikker iz a goy," a gentile is a drunkard. "Goyishe naches" describes the kinds of things that a Jew mockingly presumes only a gentile would enjoy, like hunting, sailing and eating white bread.
Nahma Nadich, deputy director of the Jewish Community Relations of Greater Boston writes: "I definitely see goy as a slur — seldom used as a compliment, and never used in the presence of a non-Jew" adding "That's a good litmus test: if you wouldn't use a word in the presence of someone you’re describing, good chance it’s offensive."
