What is Shul?
1.
Cool, especially in a Jewish way.
(Traditionally means a Jewish house of prayer, see other entry.)
Hey, did you meet the new gabbai? His waterproof tefillin case is pretty shul!
These bagels don't have a hashgacha (kosher certification), but my rabbi says they are totally shul.
My professor says that I can't get an extension because of Rosh HaShanah. That's so not shul!

Yiddish slang for synagogue. Orthodox Jews will often use this term.
Oy vey! We're late for shul!
