Term describing the phenomenon of when there is a chill vibe between 2 (or more) people who engage in intercourse. HOWEVER there is no friendship involved, just a mutually positive association between sexual partners. Fucking is not the sole aspect of all interactions and some other benefit comes from time spent together (i.e. conversation, life perspectives etc.).
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.
