look up any word, like spook:
Someone who still participates in Seventh Day Adventist activities, such as going to church, but has personally rejected belief in God. Often feels that they cannot tell their friends and family about their lack of belief for fear of rejection.
Dude 1: Gotta go to church now.

Dude 2: Why? You don't believe in it.

Dude 1: Yeah, but the wife doesn't know I'm a Seventh Day Atheist.
