A phrase used to highlight the ignorance, foolishness, or outrageousness of another's speech or actions. This invective is designed to ridicule and confuse the target by simultaneously likening him to both positive and negative role-models. It may prove particularly effective when used upon ignorant Americans, who may be unaware that the celebrated Renaissance-era images of Yeshua ben-Yosef (Jesus's birth name) were actually portraits of people the painters knew in their real lives (e.g. - relatives and friends), and which images were not based in any way upon descriptions of Jesus's appearance found in The Bible. The fact that Biblical accounts generally describe Jesus as dark-skinned, with hair the texture of wool, heightens the sardonic effect.
If someone cuts you off in traffic, pull-up alongside them at the next stop light and yell, "That's OK, Jesus was a nigger, too."
Something that white supremacists skinheads do. It involves faking cancer so that the black guy you're approaching doesn't run away, so then you can hang him.
