When someone eats some sort of string such that when one takes a dump the shit is formed on the thread of string, and when exiting the anus performs a bungee jump-like action in the toilet bowl.
Hey dude I was watching the fishes in the aquarium and i ate a string and my shit was totally bungeedumping!
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:
Shackteâu - We thought it was an abandoned shed until the realtor called it a rare alpine Shackteâu with unobstructed views and listed it for $2million.
