skanktimonious

Adjective to describe a judgmental woman who presents herself as an upstanding religious person, and talks a lot about "family values," but who has a double life that includes many violations of the principles she purports to uphold, including, but not limited to, sexual transgressions.

"Did you hear that Maisy cheated on her husband after the Christian Fellowship meeting last week?"

"That can't be possible. She is always saying people who go outside of marriage are condemned to life in hell."

"It is true. But ever since she got the implants, she has been a skanktimonious bitch."
