look up any word, like donkey punch:
 
1.
like christianity vs catholicism,
Yehudianity (vs yehudism) is a laidback conglomeration of jewish practices, with a smattering of other peoples traditions, like chistmas, thrown in for fun.

Basicaly a feel-good version of yehudism similar to reform, but more true to jewish principles (like not getting tattoos, resting on the 7th day, kashrut, literacy and a knowledge of history, sunday school, torah of some sort, and all the cool jewish holidays...)
"dude, wtf's your religon?!"

mumbled reply:
"Yehudianity"

or

"wow, those yehudians sure are cool! I'm gonna setup a trust fund promoting their cause. Yeah!"
