Octojewn
An octojewn is someone who is only 1/8 Jewish, but they act like they’ve been Jewish since the beginning of time.
My octojewn uncle shows up every year and acts like he’s the king of Passover.
She’s got 1/8 Jewish blood and still thinks she’s the most important person in the family.
He’s an octojewn and still thinks he’s got the best holiday food.
