Omegalomaniac 

From the last Fall Out Boy single before their undefined hiatus, Alpha Dog. It goes with the word "megalomaniac," which is basically thinking your the shit, with the o added on the front so it looks like "omega" (To go with Alpha Dog). It's actually quite a good song.

Omega Verse 

The dark side of {fanfiction]...

An AU (Alternate Universe) where there are "Alpha" people and "Beta" people and "Omega" people, etc. In this AU, Omegas go through times of the year/month (depending on what you read) where they are "in heat" like animals. They need to be "knotted"- when an Alpha has sex with them and comes inside them- to feel release from pain. Depending on what you read, the Omega may require this more than once or just once. Alphas cannot resist the smell of an Omega in heat and will try to have sex with them. Betas are very common, Alphas are somewhat rare, and Omegas are rare, making them valuable. In some stories, Omegas are treated like gods because the best sex is with an Omega. In other,s they are treated like animals or slaves, sold, caged, traded, etc.

This genre of smut fanfiction was started in the Supernatural fandom and spread to Anime fandoms like wildfire. Omega verses are most prevalent in Anime fandoms, particularly Fairy Tail, Blue Exorcist, and other, mostly fantasy, Animes. You can still find it in the Supernatural fandom, however.

There is a lot of stigma surrounding omega verses that portray the Omegas as slaves due to themes of rape, sexual violence, and just non-consensual sex in general.

If I were you, I'd stay far, far away.

Person A: "Hey, what's your favorite fanfic trope?"

Person B: "I'm really into the Omega Verse stuff."

Person A: "Oh my god, that's really disturbing!"

Person B: "What can I say? It turns me on."
