(Halo) Reach Fever

The disease you tell your friends, co-workers and boss that you have when you stay home from school to play Halo Reach. The person with Halo Reach Fever usually wont include the word "Halo"

Nick: Dude, why weren't you at school today?

Milan: *fake cough* (Halo) Reach Fever, man. That shits pretty intense.

Nick: I heard about that shit. It's pretty deadly.

HALO-addiculitis

Chronic disease associated with excessive Halo game play. Symptoms include but are not limited to:
1. Abnormally large thumbs
2. Degradation of visual aquity
3. Disturbed sleep patterns
4. Destruction of family life
5. Reduction in active vocabulary (increase in the use of sword bitch, noob, epic fail
6. Daily challenges become more critical than daily chores (feeding your game score > feeding your kids)
7. Reaching the next higher rank becomes the most important priority in your life.

A-Train, once a promising Industrial Engineer, has since achieved the rank of Halo Legend. Doctors and scientists have attributed his epic downfall to HALO-addiculitis.
The prognosis is grim as there is currently no known cure for this chronic disease.
Symptoms may be alleviated by giving a diseased whore a Cleveland Steamer
