Grandmaitis can be defined as the symptomatic physical response to going to grandma's and getting fed too much. The bloated stomach, burping, groaning and undoing of pants (not to be confused with Turkey-Coma)
Oh man! I went over and she fed me five meals in one day! :-p Oh man! I have Grandmaitis and can't breathe! If I eat anything else I'm going to barf!
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.
