When a certain thing or person acts in a gay fashion (slang: Stupid; Idiotic, Jose), this phrase can take the place of one such as "You are a gay fag."
If I said "You are a gay person," "If _____ was a boy it would like other boys," could be substituted instead. For example "If Pikachu were a boy it would like other boy Pikachus."
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.
