Halo Flu 

The sickness that is obtained from purchasing the newest Halo game for the Xbox 360. To get better you must stay home and play as much Halo as you can, for one to possibly two days depending on how severe your need to play is.

Man, last night I bought Halo 3 and came down with the Halo flu the next day!

Halo 3-saurus 

A book that lists synonyms and antonyms for the 'Halo 3' language

When I looked up 'Master Chief' in the Halo 3-saurus, the synonyms were 'bad-ass' and 'nobody's bitch', and the antonyms were 'kittens' and 'Mr. Rogers'.

halo roofie

The act of adding a roofie to the alcoholic beverage of someone you wish to corrupt. Usually in a professional or social situation. The target then acts in a non-professional manner, rendering their reputation (their halo) as questionable at best.

Joe: Dayum, my co-worker was out of her mind last night, hanging on every guy, taking her clothes off, and passing out under the kitchen table. She normally doesn't act like that, i wonder if someone slipped her a halo roofie, she was kinda moving up the corporate ladder way too fast...
