The act of leaving your female (or male) sexual partner in a "sticky situation", and while he/she's cleaning it off his/her chest, you douse him/her with a fine feast of brothy vomit. Then you walk out on the bitch/faggot.
My roommate Ryan, from Long Island, totally left some long island clam chowder running down that bitches' torso. He is truly a man amongst men. All Hile Ryan, the Surfer Kid!!!
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.
