Stigginit is a portmanteau of the phrase "sticking it to the libs (liberals)." The word apparently originated on Fark.com as a way to mock the practice of some conservatives who engage in a practice not because of merit or self interest, but merely because the practice is opposed by a liberal, especially in those cases where the practice is clearly against one's self interest.
Those libs want to raise the minimum wage, and even though I work at McDonalds I'm going to vote Trump because Stigginit!
Slang form of "sticking it." Used to describe opposition motivated purely by spite, usually not in one's best interest. Can become its own reason for action.
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.
