Guys who come over everyday and spend 8 hours playing Halo 2 online. They tend to trash your apartment, eat all of your food, and yell at the television. These guys tend to lack any interaction with females and tend to be alcoholics.
Halo Guy One: Let's go over there and play Halo.
Halo Guy Two: Well I do have Japanese homework.
Halo Guy One: Don't be gay, I mean it's Halo, there's nothing more bad ass than shooting people and sounding like a baboon in heat.

Get the Halo Guys mug.
Used to describe a person who is really good at Halo 2. The nickname is often used if the person's real name is either hard to remember or hard to pronounce, or if you just don't want to remember their name.
1. My friend Michael Crismon is really good at Halo 2, so everyone calls him "Halo 2 guy"
2. No one really knows his name, so we all just call him "Halo 2 guy"
