Nebby

A person that acts dumb or stupid, without sense or knowledge of what they are doing.

Gosh, I hung out with Yossi the other day and he was acting so Nebby I wanted to shake some sense into him.

Chabbadath

A Shabbat spent at a Chabad house whilst travelling or backpacking. Usually involves lots of great food and good company.

Oh yeah I was travelling around Asia and Australia and I would sometimes go for a Chabbadath at Chabad
