A party, mainly and usually consisting of boys and/or young men living with their mothers, where the Xbox titles "Halo" and/or "Halo 2" are derived as the main source of entertainment. Snacks and refreshments are optional.
I went to Jake's party, which turned out to be a Halofest.
Nah man, it's not a sleepover, it's a Halofest.
