Used to describe somebody who is TOO TALL AND SKINNY for life on this Planet we call Earth.
It doesn't matters why they are tall and skinny be it their Genes or time spent on a stretching machine while being tortured by Elves from the Spooky Wood down Hobbs Lane.
If they are too tall AND too skinny, they may be referred to as a Lanky Streak of Piss.
A current example is the England Footballer Mr Crouch whose name indicates what he does a lot of.
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 $2 million.
