An advanced sex act where the male ejaculates into the air, and proceeds to catch the jizz in his asshole. After this he takes a semen infused shit on his female partner's chest. The shit then rolls down the woman's abdomen and into her vagina where she then becomes impregnated by the sperm from within the shit.
"Oh my god Nancy, you're pregnant?!"
"Yeah, Brian Goose Egged me on our anniversary!"
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:
