Similar to "brown bagger", but the whole body, not just the face needs bagged or "cinch sacked." May even pertain to someone's overall rotten personality, appearance and general place in the world.
Me: "Hey man, that dude looks horrible."
You: "What a cinch sacker!"
or
Me: "I hate that stupid biatch at work."
You: "Someone should throw a cinch sack up on her."
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.
