1. A disk (or a ring, more recently) above one's head, usually used in religious context. A halo usually indicates that the one below the halo is a good person.

2. A video game series developed by Bungie Studios, starting with Halo: Combat Evolved back in 2001. Combat Evolved is widely recognized as the game that single-handedly brought attention to the Xbox. Halos 2 and 3, released in 2004 and 2007, respectively, were very well received.
The series' popularity led to two spin-off games, Halo Wars, developed by Ensemble Studios rather than Bungie, and Halo 3: ODST, essentially a filler for the time between Halo 3's release in '07 and Halo: Reach, a game set to be released in 2010. Since Halo 2, Halo's online multiplayer has been incredibly well-received by anyone who doesn't have a shit connection.
Many gamers think Halo is an overrated and generic FPS. Generally, the rest seem to think that Halo is the greatest thing ever to grace their souls. There is an equilibrium, which is the reasonable players who feel that enjoying one game does not make you 100% exclusive.

Canonically, the correct timeline for Halo is:
Halo Wars
Halo: Reach
Halo: Combat Evolved
Halo 2
Halo 3: ODST
Halo 3
