When two or more guys are hanging out and a hot girl walks in, one might exclaim 'Boob Shotgun!'. This is related to two people walking to a car and one calling 'shotgun', therefore claiming the passenger seat. Exclaiming 'boob shotgun' means to call dibs on a girl, especially of the boobs.
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.
