FireWall

Either a tool used to protect your computer from outside invaders, or a complete jackass who pretends to be a programmer in just about every language other than Visual Basic. Makes himself feel better by creating false definitions of people with a higher capacity of thinking than his own. Tends to think that Windows, despite it being the most popular Operating System in the world, is a horrible platform to dev for (as if it would matter for him).
Uses strange misspellings of words in order to seem cool, but it does the opposite.

"FireWall ([e-mail]) has left #DigitalUnderground (ooo0ooo, a FireWall just blocked your biznitch ass. What cha going to do biznitch?)"

FIREWALL

A secret stash of blow that someone hid so that later in the night when everyone is out of coke you still have a little firewall as a bonus that no one knew about.

"We are out of lines" "Nope I have a firewall."
