While at the movies, you take a tub of popcorn and make a hole at the bottom. Then you stick your dick through it and while watching the movie, your date sticks her hand in it as if to grab popcorn. This will look that way to the movie-goers around you. In reality, she jerks you off inside the tub until you cum all over the popcorn and then she eats it. Hence: butter the popcorn.
Sean: "I'm taking Melissa to the movies tonight. You know how easy she is, so I know we are going to butter the popcorn. I'll text you tomorrow and tell you all about it in complete detail. I'll even save you some of the popcorn."
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.

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.
