I. When sending a pornographic link over IM, appropriately tag it
sfw or nsfw.
II. Never admit to a dude's chick the existence of the dude's porn collection.
III. When you lend a dude's chick some
money, the dude is responsible for reimbursement,
even after he breaks up with the chick.
IV. If you're ever so lucky to find nudie pictures of a dude's
hot girlfriend, you are obliged by the Dude Code to, in all discretion, share them with other dudes. (note: via e-mail or IM only!)
