When two people stick a boba straw between their assholes, and share each other's natural gases in a act of ultimate submission to one another.
"Hey bro, I'm feeling down and need someone to do a Natural Gas Pipeline with."

"Thanks man, I'm so glad we can share our gasses with each other, I love you bro."
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.
