When you have sex with a girl, then finish on her vagina. Spread the semen over her vagina and leave it to dry. Once it dries, nothing will get in or out of her vagina, leaving it "beaver dammed"
last weekend i beaver dammed my girlfriend, needless to say she was not happy when she realized what i had done.
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.
