Halo Junky 

An individual who is obsessed with the video game series Halo. So much so that it develops into a habit and addiction.

"Man let's go party tonight!"
"Hold on, I've only got a couple of hundred more experience to go to become a major..."
"Dude, get help, you're a Halo Junky."

Halo junkie 

When a guy you date no longer wants to do anything but play Halo all the damn time and be a big ass looser!!

My husband is a worthless "halo junkie", he is addicted to that game!!
