someone used that term here and I don't know what it means.

I use the term "Happy plastic people," but it's anyone who hides their true self behind a mask of Christianity.

EDIT:
Here's where that term comes from... probably my favorite contemporary Christian song ever.

I think it's one that says they are Christian but their lifestyles do not represent that

that is a good question, i have never heard of that either, if you don't get a good answer, try sending a message to the person that used the term, maybe they will answer you. i'm a christian, and i have never heard anyone say that before, maybe that person just made that up. good luck .

I don't know but it sounds sexier than just Christian.

In fact, I wouldn't have a problem with you people if you were all called the Lipstick Christians.

lol..
interesting...

goes and googles it.

LOL...I came up with Christian Dior lipstick.

Sure they werent talking make up and not religion?

like a lipstick lesbian. someone who only does it cause it's trendy.

It means they only proclaim Christianity when it suits their purposes to do so.
