What is 4Chan???
For the love of God, just let it go. It is admittedly where a lot of the funny comes from, but it is also a dark place. Chances are you wouldn't like it there.
Envision a forum where no registration is required.
And where absolutely anything may be posted.
Nobody really knows what "anything" means, until they see it on 4chan.
Seriously, El Tejon, if you should find 4chan you will most likely (paraphrasing ED here) "be driven out by an autoimmune system of guro, racism, foul language, pornography, stupidity and constant trolling."
None of that was a joke, either.
