masturbating with a marshmallow in your ass and farting and burping at the same time, hence the word "bart" = burp + fart. The fart can often be used to warm the mallow in prep for a smore.
Wow I'm having a lot of gas, I'm horney, and I would love a smore...I feel like marshturbarting
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 $2million.
