(descriptive noun) Used to describe the need for constant wiping after a bowel movement that continues to produce an incessant amount of greasy residue. It's almost like there's a brown or black marker up there, with the cap off and the tip facing outward.
"That was some markerwipe I had in there. I went through half a roll of toilet paper and a whole package of baby wipes."
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.
