Hebris

[hee-bris]
Hebrew + Hubris
noun

1. an excessive amount of pride resulting from one's Jewish heritage or one's association with Judaism; sometimes begetting the subject's eventual demise.

Ex. "I don't care if Kendall's confirmation party is the same day as my bat mitzvah, who would miss out on my Swarovski-encrusted Star of David favors?!" Rachel's hebris overlooked the fact that Kendall's older sister was Kim Kardashian, a force infinitely more enticing to thirteen year old boys than sparkly Judaica.
