Like the web, there's also the deep web. One is only just the surface, while the other dives much deeper into things you may or may not want to explore.
The deep weeb is a place for those who have dove into anime / manga like Naruto, then decided to dive deeper into the abyss in search of more anime / manga and other like minded people. The few who unexpectedly go that deep, are only met with confusion when there.
Dude1: I'm going to talk to the new kids, wanna join?
Dude2: Nah, I'm good. I heard that they're in the deep weeb dude.
Dude1: That's just a myth.
Dude2: Whatever, don't believe me. Just don't say i didn't warn you.
-20 minutes goes by-
Dude2: Hey, so how did it go?
Dude1: I don't remember much, but i think my name was Sasuke at some point. Shit was weird.
Dude2: I warned ya.
