(participial phrase) the sexual act of grabbing and twisting the head of the penis upon male orgasm in an attempt to increase seminal velocity (and make a cool spiral); the partner performing this act must make a squeaky sound as if a door knob was being tightened
Male 1: My girl was tightening the door knob last night.
Male 2: What?
Male 1: She twisted the head of my penis when I came and I let fly a mighty ejaculate.
Male 2: Does it burn?
Male 1: Yea, but it was worth it. And she's blind now.
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.
