If you're a newfag, Lurkmore = YOUR FRIEND.
Read that site and study it like your life fucking depended on it. It's the only real way to get the humor here.
Aside from being a home-bound hiki that lurks /a/ 24/7 like most of the lifeless fags on here. Some of us just don't have the endless hours they do to stay inside on a computer to HOPFULLY be on when a new joke crops up.
