reptilian brotherhood 

The highly devoted fan base of youtuber "Leafyishere". After leafy had revealed his face on his 100,000 subscriber special, fans photoshopped him to be a reptilian. Now, fans of him can be found posting on youtube and twitch.tv content related to CS:GO such things as "HISSSS" or "Leaf a Like!"

My stream was pretty chill, until the reptilian brotherhood showed up.

Brotherhood of Steel 

A group of badassess who like to shoot people with lazers and build giant robots. They wear power armor, an armor so powerful you have to be trained to use it. Also see Fallout.

That Brotherhood of Steel Paladin totally kicked my ass for no reason. He said I deserved it.

Dark Brotherhood 

The Dark Brotherhood, from the game Elder Scrolls IV: Oblivion (which is a kickass game), is an unofficial guild, or a grouping of people. These people are actually deadly assassins,who are hired by people all over the land of Cyrodiil. In order to make dealings with them, you must offer up someone's life, like maybe a family member, or someone close to you, which makes you decide if it's really worth it. The Dark Brotherhood tends to make their assassinations look as though they were accidents, but some people will suspect a lot of deaths to be their doing. In my opinion, they have the best quests and things to do.

-Did you hear about what happened to poor Baenlin? That minotaur head he had on a plaque on his wall dropped right on his head and killed him!
-Idiot, it wasn't any accident. It was the Dark Brotherhood, you should know that. Baenlin's nephew wanted that piece of estate to himself for a while now, so he requested Baenlin's death.

The Reptilian Brotherhood

The Brotherhood that consist of LeafyIsHere's subscribers. He is their Reptilian Overlord, King, Master and Dad. LeafyIsBeafy. The Brotherhood consists mostly of people without no shame and an immense desire to ruin other YouTuber's comment sections and now also lives. They do exactly as subtly and indirectly commanded by their Overlord, Leafy.

Oh look, the Reptilian Brotherhood has targeted a YouTuber's video, and now it has 200 000 dislikes and a comment section full of "hissssss", "dad sent me", "fake and gay", and "Reptilians Unite!".

brotherhood 2.0 

Youtube celebrities John and Hank Green who spent the year 2007 refusing to communicate through text. Everyday they communicated through vlogs on Youtube, alternating days. They amassed several thousand subscribers.

They extol the virtues of the nerd life, calling themselves and their fanbase nerdfighters and those who aren't nerds decepticons.

They acheived some fame when Hank's song "Accio Deathly Hallows" was featured and expressed the sentiments of nerdfighters everywhere.

Wow, did you check out the "in your pants" forum on brotherhood 2.0 yet today?
