A more badass way of saying "I'm sick and tired of repeating myself, get it through your fucking head". May also have implications of "are you calling me a liar?". From the Bruce Willis and Damon Wayans movie "The Last Boy Scout".

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:
