It sounds like a nice way to describe a cute picture of a child with a cute puppy...but it's actually when one gentleman is gnawing on the phallus of another gentleman. Generally they don't draw blood but it does happen from time to time.
Don, can I gnawwwww on your engorged phallus after you've finished that carafe of Creme de menth?
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.
