halotosis 

An afterimage type of alteration to your visual and balance processing caused by many hours staring intently at the Halo video game screen, jacked on adrenaline but barely moving your body except for your twitching fingers, navigating through dark alien-infested tunnels with a weird purplish flashlight mounted on the helmet of a wobbly android war machine that you operate via the clumsy X-Y-Z axis joystick interface...distorts your senses when walking and driving after, especially in the dark at 2am when the battle is finally put on pause...save game for later.

After dinner, he said "Slayer in Blood Gulch, or Snipers in the Power Station?" When I got up to pee, it was 2am.

"Yo dude, I gotta work tomorrow..."

"OK, but let's just clear this level and smoke another one before you go."

I had severe halotosis on the way home, with green crosshairs hovering in my field of vision...the flood was everywhere, splattering off the windshield of my Warthog as I crushed them into roadkill.

halomitosis 

A disease quikly spreading around the world. This disease makes you addicted to video gaming (not just halo). Common symptoms are lack of sleep, pretending to carry around a gun with you, threatening to shoot people with plasma guns, and calling everyone a n00b. People who suffer from halomitosis usually stay in dark rooms gaming (which leadis to their pale skin and fear of sunlight). They also hav poor social lives and are called losers.

As the Halo 3 hype grows exponentially larger, the halomitosis epidemic grows along with it. Anyone without any self control or friends hase a small chance of surviving this epidemic.
