A figure of speech used when in a playfull wrestling match. It is used to tell the opposition to back down and that you are coming in.
This can also be used if you are aggravated by a person talking in a derogatory way about someone who is dear to you so you tell them to "control-alt down fooool". It hopefully shuts them up.
Person3: Control-alt down foolimma bust some tees!
*KAPOWWWWW* raah.
Person1: arghhh mannn my ribs, duuuude watchu playin at??
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 $2million.
