I went to Jake's party, which turned out to be a Halofest.

Nah man, it's not a sleepover, it's a Halofest.

To get several people together for hours of Halo. Often lasts days or weeks. Very similar to a smash til dawn. Good Halo Fests require atleast 8 people for good 4v4 games, and cover slayers, CTF, and KOTHs. It's always topped off with all rockets at Prisoner. Sometimes lasts only a few hours due to people passing the fuck out from excessive drinking during the games.
Me: Yo, what you doin' tonight?
Bostick: Watchin' Grey's Anatomy.
Me: Oh hell no. We're havin' a Halo Fest, dude.
Bostick: Sweet. On my way.
