JewBu
In short, someone who was raised Jewish and turned Buddhist, or who is a hybrid of Jewish and Buddhist in spiritual/religious background.
My mom's a major JewBu-- one Hanukkah she was lighting menorahs like the rest of 'em. Then, before I knew it, she was reading up on the Dalai Lama and telling me to Be Here Now.
A Jewbu
Typically a (white) dad older than 45 and a liberal, his family is Jewish—probably reformed— and he is casually interested in Buddhist beliefs. He likes his podcasts.
“I saw you’re dad meditating on the porch. Is he a Jewbu?
