A scape-goat word that people use when they are too afraid of what society will think of them for saying that they don't believe in a "god".
Uber Religious Friend: "Hey Buddy, wanna go to church with me instead of hanging out and playing video games today?"
Guy who doesn't believe in god at all but is scared of what his friend will think: "ooh, I'm agnostic.. I don't think I'll go today but maybe next time!" (knowing he'll never go because he doesn't believe in god AT ALL)
