(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.
