In colloquial speech, the phrase "dicking the salsa" would be used in reference to an event, object, or person that kills the mood, or "harshes the buzz" of one or more people.
Greg: Did you see that video of that bus of puppies falling into a lake?
Sam: Dude, stuff like that is really dicking the salsa.
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.
