It's like in the movies, when the bad guy is blackmailing someone, telling him the side where to drop the money, and he's telling to do no wrong moves (no wrong moves = no funny stuff)
Drop the money in the yellow garbage bin in front of the post station. Think about your wife, so "no funny stuff".
if one feels that the comment/remark or passed event strikes them as something humerous one simply states the word "funnystuff". commonly used to replace laughing and normally ends said conversation
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.
