A person who professes faith when in fact that faith does not exist in order to gain acceptance 2. to move covertly among a community of tight knit faith (such as Hasidic Jews or Mormons) for business purposes or for other personal gain. 3. A person who suddenly adopts a religion (temporarily) for the sake of a favorable outcome in a court proceeding.

Ex. 1, "She's not even Jewish at all, she just wants to hang around Favel's sisters, everyone knows she's a fathiest except for him."

Ex. 2, "Why did she take communion? -We were just arguing about how she thought it was stupid and never got confirmed; damn fathiest!"

Ex. 3, "I realize that I have taken vows of celibacy, but now I shall un-take them with this harlot here, for I am a fathiest."

yo, did you see those filthies in the BMW?

fintheist 

A Fintheist is a former theist who has left religion and is done with theism (belief in gods). This differs from atheism in that it isn't just non-belief, but former belief.

No, I'm not a lifelong atheist. I'm a Fintheist who stopped believing 3 years ago.
