First of all anyone to use this phrase is simply worthless. The average teenage AIM user is so
lazy they don't have the time to type "
haha" in reference to something funny. But now they resort to more desperate measures to be ridiculous they
add a "z" to an already terrible phrase. I am assuming it refers to something like LAUGHING OUT LOUD, ZORO, or, LAUGHING OUT LOUD
ZEBRA. Which simply translates into I am worthless and should not be alive, and the least I can do for the world is leave.
