efileni 

Very beautiful girl who is well spoken. Many guys like her but are too afraid to make a move because she is smart, beautiful, and a little sassy at times. She is a sensitive girl who wants everyone to get along. Get you and Efileni. She is one of a kind.

Boys: I wish I had an Efileni. She seems overly confident. Someone help me. She’s too beautiful.

Neo-efilism

It's a extended or an advanced version of Efilism Claiming that the only true solution to the universal problem of pain and suffering is through The Painless Extermination of all Sentience Life Forms In the Universe Called (The Neo-efil Final Solution or Der neo-efil Endlösung) The likes and adoption of a nazi style, the seriousness of this philosophy is questionable as it's created by an anonymous troll called efilperpenfuhrer Eric Brown.

The only logical and practical form of Efilism is Neo-Efilism In Theory At Least.

Good, Sehr Gut Herr efilperpenfuhrer.

efilism 

Efilism is a word invented by the YouTube user inmendham to describe the reality that once living things gain sentience, any perceived value is biologically self-serving and therefore a waste.

Efilism is the next logical step after understanding Anti-natalism.
