The act of grabbing you're scrotum mid-coitus and shoving it into your partners mouth or gaping anus. Typically followed by a commanding statement for your partner to "Save em up for Winter!"
It should be noted that this dominating act should only be performed in situations wherein the dominating party has enough Sack Slack to properly perform the maneuver and the receiving party has either a big enough mouth or a properly stretched anus to receive the package in its entirety.
Me and Angie wanted to try something different last night so I tried Squirrel Cheeking her ass and told that bitch to save em up for winter.
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.
