Awesomerificaltasticness is the word applied to anything beyond the realm of awesomeness. If it is also not quite terrific or fantastic, (which are part of the word) then it's Awesomerificaltasticness.
A Shackteau is a humble, weather-beaten, structurally questionable shelter located in a spectacular or highly coveted place—Wales, Jackson Hole, Sun Valley, Crested Butte, coastal Maine, the Alps—where the building itself may be worth almost nothing, but the dirt, view, access, and mythology make it absurdly valuable.
