look up any word, like thot:
 
1.
The feeling of a wistful desire to return in thought or in fact to a former Halo experience or game, to one's past Halo-dedicated and obsessed life where the only thing that mattered was pwning n00bs with friends, or to one's Xbox Live family a.k.a. the long disbanded Halo 2 clan; a sentimental yearning for the happiness that only the Halo franchise brings with its cooperative campaign, hours of multiplayer and the lack of a social life or girlfriend/boyfriend.
Person A: "Dude, Billy has been listening to the Halo soundtrack all week."
Person B: "Yeah, he's been really Halostalgic before Reach comes out."
