A shart (a fart accompanied by some liquid poo) exploding from the anus following the consumption of greasy fast food such as Mcdonald's, Long John Silver's, or Kentucky Fried Chicken.

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:
