Obvious Jew
An OJ is a Jew you can spot from a mile away. They usually have names so Jewish, they might as well be wearing a kippah. Don’t go around writing them down like they’re on a list unless you're totally sure they're a real Jew.
'He's got a name like Daniel. He's an OJ, no doubt.'
'She’s got a name like Rachel. That’s an OJ.'
'Ezra? That’s an OJ. No need to question it.'
