a Watermelon Fucker is a dude who well.. Puts a hole in a watermelon and fucks it. These type of people are actually not that common and are mostly used in Packing ( another way for saying Argument ) and just calling someone a name in general.
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:
