"Judism is a heresy of the Earth Mother-Sky Father religion."
When I was in college, one of my buddies, a Jewish guy, dated a girl called "Earth Mother", a large woman. I doubt she's the one you're referring to, though, as they never fought about religion, at least she never called him a heretic.
You could say he was 'mooning' over her...
There's a Black racist cult called the Five Percenters wherein the men refer to themselves as "gods" and the women as "earths".
