If you can read this you need to get laid. Its "1337" or Elite speak... It started off in binary coding and a lot of teenager wannabe hackers developed it into a semi-shorthand that is widely used based on different fonts...
Language is ever evolving and this is considered for a new language. Dead serious...
Its supposed to be a joke referring to the fact that if you can read this "1337" speak you spend too much time on the computer and should go get laid... But I can read it and Im married. I have no shortage of nights without sex when my wife chooses to give it to me.
