A phenomenon that occurs when a piece of media (mostly video games) is put on hiatus or when there is a very large gap inbetween releases, where people will overhype and praise the content to the high heavens, even before release. It then either doesn't get released or does get released, causing everyone to be
disappointed because their soaring
expectations weren't met, that weren't very realistic in the first place.
This isn't the doings of the developers, this is the doing of the community who in an attempt to keep their hopes up, make excuses about their favorite piece of media being or soon becoming
the greatest piece of entertainement ever, e.g. Half Life 3. Aforementioned hopes are then usually crushed and they go to metacritic to rate the item a flat 1 or 2.
