The space in between the top of a girl's legs directly against the vagina. Measured in finger-widths from behind. 3 fingers is the perfect width for a flat spot. If a girl has a 4 finger flat spot she is probably bow-legged.
I won't fuck a girl who doesn't have at least a 2 fingerflat spot.
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.
