You're still living at home I take it?
Plan on the carpets getting fucked up, one item being stolen and finding puke in at least three places. Just accept it, no matter how careful you are, some shit will go down you won't be able to fix. Start thinking of excuses now.
Do yourself a favor and lock all the bedroom doors unless you want your homeboy wiping off his dick on the curtain/pillow after he poopenhausens that new girl in your mom's room. Also, lock up the pets and HIDE the expensive shit in a locked room's closet.
Plan ahead as to what you want to go down. If you have an ice luge, a fog machine, a DJ, pyrotechnics and a foam generator, don't expect the cops not to show up- so don't get carried away unless that's the point.
One person lights up a cigarette, everyone will. Taze the first person who does it.
People you know are shitbags will show up. Throw them the fuck out immedately. They might behave for ten minutes but let's be honest.
Have a black magic marker on hand. Trust me, your friends will look awesome with cock sideburns and a ballsack chin once they've been outpartied.
Be sure to secure the cute girl crew for the afterparty, and keep a few bottles of the finest $4 champagne on chill because it's fuckin' fun to pop a couple bottles after you throw everyone out and turn your attention to getting some tail for you and the crew.
Make sure your friends stay over to help with cleanup. You'll want help, because if the night went really well you aren't cleaning up a fuckin' thing before bed.
Last, DO NOT invite me. I'll upper deck your toilet like whoa, and I'll sharpie shit on your face that would make your mom cry. Good luck dude!
