I know Newgrounds has all kinds of different opinions on 4chan. Some think its fun, some think it sucks, and some haven't even been there. Let me clear some things up for you.
/B/ is the asshole of the universe. The reason they say that is because its not full of shit, but because they laugh at anything. Animals getting raped and burned? HA! A weird creepy disease? They make jokes about it.
They are anonymous. They do not forgive, they do not forget. It can be funny, but you have to have that special kind of humor, like NG, to have fun. If you don't, you will think its a creepy place full of weirdos and rapists( Which it is).
Almost everything funny on the internet comes from /B/. That means almost all memes, fads, and spam. Go here and look at some of them. Look up anything else you want to know, and you will find it.
I don't want this place to turn into 4chan, at all. I'm just saying to learn up your memes, and understand what they are. I remember being a new user and seeing pictures, and sayings, and not understanding them.
Also. Read it, you fags.
