Used to ask someone for (or to return) a favor. Deriving from weed culture for when someone lets you smoke their weed with them for free, is now often used to ask for any kind of favor.

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:
