Essentially "good riddance" to bad luck. One would utter this phrase when confronted by a black cat, seeing a hearse or any other situation thought to bring about bad luck.
Person 1: Woah look! It's a hearse!
Person 2: Solavaya (makes a hurried gesture)
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.
In use:
