When a person is too old to go trick or treating, (usually at age 16) but can't resist the allure of free candy, they take a small child trick or treating so they themselves can go.
My parent told me I was too old to go trick or treating, so I used my friend's little sister as a scapegoat and went and Co-op trick or treating!
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.
