Atheostica 

The holiday celebrated by atheists while others celebrate Christmas or Chanukah.

"For the last few years I've been feeling a little awkward about wishing my boyfriend, an atheist, a Merry Christmas. So, this year I'm gonna try out 'Have an Indifferent Atheostica' & see how that feels."

Atheistic Morality

Doing the right thing because it is the right thing to do, not because you want to gain favor with god.

Religious Person: I gave money to charity because god would want me to.

Sane Person: I gave money to charity because some people needed it more than I did.

Religious Person: Why would you help someone for no reason?

Sane Person: it's called Atheistic Morality, learn about it.

Atheistic 

Atheistic is the quality of being atheist. That is to believe that there is no god. Though the customary response for many logical thinkers and scientific types it falls prey to the same logic flaws of religion as it is, ultimately, a belief and has neither been proven or dis-proven.

Atheistic person: "look up there!"
Jehova's witness: *looks up at sky "there's nothing up there"
Atheistic person: "Exactly"

Atheistic Buddhism 

The belief that no God or deity exists out of the context of physicality, in the same way a traditional atheist does. The Atheistic Buddhist however does follow the ways of the Buddhist philosophy.

Religious person: Hey! What religion do you believe in?

Atheistic Buddhist: I am a follower of Atheistic Buddhism.

Religious Person: What's that

Atheistic Buddhist: I don't believe in any God or Gods, but I still follow the teachings of Buddhism.

Religious Person: Ah! Interesting!

Atheistian 

An atheistian (atheist + Christian) is a stereotypical militant atheist who essentially treats atheism like a religion.

While atheistians will of course deny that atheism "is just another religion", they have a set of unwritten rules which they expects all members of the "atheist community" to follow

Basically a "true atheist" (according to atheistians) is a person who is one or more of the following - a communist, socialist, liberal activist, radical feminist, tree hugging environmentalist, welfare junkie, emo kid, goth, computer geek, fat fuck, virgin, homosexual, weeaboo, D&D nerd, social reject, aspie, basement dweller, or just a straight up whiney-ass loser in general who bitches about "atheist persecution" but is less tolerant than a lot of fundies.

Any atheist who doesn't fit this stereotype (ex. supporting gun ownership rights, not voting for the Socialist Party, playing sports, having a sex life, enjoying mainstream movies and music, not sporting a neckbeard, etc) is considered on par with a religious heretic by the atheistians and despised even more than Christians.

Atheist dude: I'm a big fan of Bill Maher. Anyone else here watch his show?

Atheistian 13 year old virgin: What??? Bill Maher??!? You're a fucking ignorant moron to watch that douchebag! That guy spouts anti-vaccine propaganda and he's a horrible representative for the atheist community, and you're as ignorant as he is for watching his pathetic show. STFU moron.

Atheist dude: ...uh hey dude, Bill Maher's actually a deist, not an atheist.

Atheistian 13 year old virgin: ..what what? Uh nevermind I don't care. You're a moron and you'd make a great creationist considering how fucking stupid you are. Quit giving atheists a bad name, you fucking moron. I'm going to ignore you from now on, you fucking idiot. Bye.

Atheistic Existentialism

Atheistic existentialism, existential atheism, or atheist existentialism, is a type of existentialism that explicitly excludes any transcendental, metaphysical, or religious beliefs from philosophical existentialist thought. A person of this belief is most likely going to be a positive atheist. This type of existentialism overlaps with existential nihilism.

Atheistic Existentialism includes philosophers such as: Jean-Paul Sartre, Albert Camus, and Friedrich Nietzsche

aetheostic 

agnostic + aetheist, if you're an ignorant redneck republican

I mocked their use of the English language, so they called me an aetheostic.
