A female that has had sex (esp. unprotected) with many, many different guys. This "slutload" usually has bleach-blonde hair, wears low-cut shirts (as to show off their giant tits), discusses to her classmates the number of guys she's blown, talks in a sexual manner most of the time, and has many slutload friends. These females should be avoided at all costs. They usually think they're cool because they listen to Dance Gavin Dance, The Devil Wears Prada, Attack Attack!, 3OH!3, and other lame bands.
Joshua: "Wow, that girl Kendra sure is a SLUTLOAD"
Sebastian: "She sucked your dick, too?!"
Joshua: "Yeah man. And hey, did you get that naked picture of her?"
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.
