When you're fucking a bitch missionary and you're squeezing her tits hard for an advantage point, and right before you cum you barbaricly tear her breast implants out cum in the two new holes you have just made and replace them with the last girl's you did it to.
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:
