JOHN: Hi, there.

This is John Green. HANK: And I'm Hank Green, and we are the Vlogbrothers on YouTube. JOHN: And we are making this video a Frequently Asked Questions video for the purposes of answering some questions that are frequently asked.

HANK: People are often confused. Like, for example, what is a Nerdfighter? JOHN: A Nerdfighter is a person who, instead of being made out of, like, bones and skin and tissue is made entirely of awesome.

HANK: So what you're saying is that Nerdfighters don't fight nerds? JOHN: No, we're clearly pro-nerd. HANK: Nerdfighter is basically just the community that sprung up around our videos, and, basically, we just get together and try to do awesome things and have a good time and fight against World Suck.

JOHN: What's World Suck? HANK: World Suck is kind of exactly what World Suck sounds like. It's hard to quantify exactly, but, you know, it's, like, the amount of suck in the world.

JOHN: One of the questions we get asked the most is 'Do you guys have real jobs?' HANK: Yes! JOHN: Well, I mean, it depends on how you define "real". Hank runs the environmental technology website EcoGeek.

HANK: John Green is an award winning author. He has written books such as Looking For Alaska, An Abundance of Katherines, and Paper Towns, and he's won many awards including the Edgar Award and the, the Printz Award. HANK: Why don't you blink?

JOHN: I don't blink because I'm focusing when I'm in front of the camera. I do blink in real life. That's why I still have eyes.

And, also, it's sort of a tribute to the original video blogger, our hero, zefrank. [John and Hank bow] JOHN: So, Hank, what's DFTBA? HANK: DFTBA is an acronym. JOHN: No, it isn't!

It is not an acronym. Acronyms are pronounceable. It is an initial-ism. [Both try to pronounce DFTBA] HANK: It's an initial-ism that stands for Don't Forget To Be Awesome.

JOHN: Am I too young... HANK: ...old... JOHN: ...fat...

HANK: ...skinny... JOHN: ...weird... HANK: ...cool...

JOHN: ...nerdy... HANK: ...handsome... JOHN: ...tall...

HANK: ...dead... BOTH: ...to be a Nerdfighter? JOHN: No!

If you wanna be a Nerdfighter, you ARE a Nerdfighter! HANK: Nerdfighter dictionary time! JOHN: Lightning round.

HANK: Puppy-sized elephants. JOHN: We asked natural selection to make us puppy-sized elephants because they would have the evolutionary advantage of being adorable and we are waiting for that to happen. JOHN: Stuff on heads?

HANK: Yeah, if you put stuff on your head, it makes you feel better about life. JOHN: Nerdfighter gatherings? HANK: Is when Nerdfighters get together.

Sometimes we're there, sometimes we're not. JOHN: French the llama? HANK: French the llama is something that John is trying to make into a thing, in which people say "French the llama, that whale is big", but it's not gonna work.

JOHN: Oh, it's gonna happen! I'm gonna make french the llama happen! HANK: Puff levels?

JOHN: Uh, my puff level is the level of puff in my hair which gets higher as I get more stressed out. HANK: Decepticon? JOHN: Is the opposite of a Nerdfighter.

JOHN: Giant squid of anger? HANK: Is basically like a YouTube troll [waves arms]. JOHN: Tiny chicken disease?

HANK: Is a disease that happens when there's tiny chickens in your head and they lay eggs and all of it ooze of your nose. It's actually... JOHN: It's a common cold.

HANK: Yeah. JOHN: Secret siblings? HANK: Secret siblings are anyone who makes video responses down here to our videos.

JOHN: Down here, in my pants [points down]. HANK: In your pants? JOHN: "In your pants" is a phenomenon discovered by Maureen Johnson.

If you add "in your pants" to the end of book titles, those book titles become much funnier. 'The Sun Also Rises... In Your Pants' HANK: 'A Spot of Bother... In Your Pants' JOHN: Notsome?

HANK: Notsome is the opposite of awesome. See also Fail Puppy and the Fail Boat. HANK: The Yeti?

JOHN: Is my wife. The Katherine... HANK: ...is my wife.

JOHN: Oh, and this... [makes Nerdfighter sign] HANK: Ah... is the Nerdfighter gang sign. So if you see somebody doing this you know not to shoot them. JOHN: We have created a playlist of 20 Vlogbrothers videos that you can watch that will give you a broader sense of what's going on in Nerdfighteria in case you're new.

HANK: And if you have any friends that are a little bit confused about why you're watching two nerds make videos about Star Wars and giraffe love and making the world a better place through video... JOHN: Those, those are three interconnected ideas. HANK: ...then you can send them to this video right here so that they can get a little bit of a debrief before plunging in to the rest of our stuff.

JOHN: Now the playlist is on the screen and we gotta do like a little playlist song. BOTH: [singing playlist song] JOHN: Now, did you just write that, because that's really good. That's brilliant.

Did you, like, did you come up with that off the top of your head like that? HANK: [continues singing] BOTH: [laugh] HANK: It's like Mario swimming [sings]. JOHN: Nerdfighteria, thanks for being awesome and thanks for all the support you've given us as we continue into our fourth year of making videos.

Best wishes! HANK: DFTBA!
