My way of saying 'kid'. ex) like omg kid "key-yid-aa" whats wrong with you?

A Jewish person, especially an Ashkenazi one.
Sometimes used as an antisemitic dog whistle, however the word itself is not offensive and shouldn’t be deemed so. It means “Jew” in Yiddish.

A very righteous and holy Jew who's generally a follower of the orthodox sect of Judaism. Basically a mitzvah observing Jew.
