Fedatheist 

An individual who chooses to define him/herself as an atheist for the sole purpose of being accepted in atheist culture, thus getting attention, and the feeling of superiority over others, while being mostly or entirely ignorant to the actual beliefs of atheism. This lifestyle is achieved by the said Fedatheist acting generally rude and annoyed by others, frequently boasting of their wit, edgy personality, or anti-religious thoughts, and of course, wearing an unflattering fedora in an effort to look intelligent, introspective, or, as aforementioned, edgy. Optional additions to the lifestyle that typically enhance ones efforts at Fedatheism include Brony paraphernalia, an unkempt neckbeard, fingerless gloves(preferably black), an ultra-liberal political stance, pocket chains, and alleged membership with the internet hacktavist group Anonymous, usually in cohesion with a Guy Fawkes Mask. Fedatheists are commonly found a variety of internet forums in comments sections, having overzealous arguments with others, and regarding any belief besides that of atheism as utter stupidity and a crime. Fuck Fedatheists. Buncha dickweeds.

Normal Human Being~ "Who here would like to have an intelligent conversation about various religious aspects?"

Fedatheist~ "FUCK YOU AND YOUR FAIRY-TALE, OPPRESSIVE, FAG-BURNING BULLSHIT, YOU FUCKING FUNDIE PLEB. I HOPE YOU GET CANCER AND YOU PRAY TO YOUR NONEXISTENT GOD TO FIX IT FOR YOU. YOU'RE THE REASON YOUR PARENTS GOT DIVORCED AND HUNG THEMSELVES, BECAUSE THEY COULD BARE TO HAVE THEIR EUPHORIC INTELLIGENCE STIFLED BY THE LIKES OF YOU WITH YOUR NONSENSICAL BOOK OF LIES WRITTEN BY CRETINS 2,000 YEARS AGO. THE ONLY GODS I PRAY TO ARE CARL SEAGEN, BILL NYE, AND NEIL DEGRASSE TYSON. I HOPE HELL DOES EXIST SO YOU ALONE CAN BURN THERE IN YOUR RETARDATION OF A BELIEF. NOW IF YOU'LL EXCUSE ME I'M GOING TO 42O BLAZE IT, FUCK MY RAINBOWDASH SEX PILLOW, AND MAKE A RAGE COMIC ABOUT HOW I PITIED YOUR MEANINGLESS EXISTENCE. MAY DARWIN HAVE MERCY ON YOUR FUNDIE SOUL."

Normal Human Being with appropriate response~ "Jesus Christ dude. Calm down."

Falatheist 

An atheist that has learned latin words and philosophical fallacies and proceeds to

1) Use them in every single conversation, regardless of the audience
2) Call out others using them without understanding what they actually mean
3) Mention and be guilty of the same fallacy in the same conversation

Atheist #1: "Look, let me explain this to you again, as I've done before, but slower this time, your premises are flawed because..."

Falatheist: "HEY! That's a pretty disrespectful tone, typical Ad Hominem tactics!"

Atheist #1: "I don't want to get off topic, but that's not actually what Ad Hominem means, and I get the feeling that beneath your sesquipedalian loquaciousness you're the same kind of fundamentalist intent of winning arguments through Argumentum Verbosium, which is why you're points are probably not worth listening to.

Falatheist #1: Look who is a Falatheist now!
