This phrase is similar to the commonEnglish phrase "are you yanking my chain?" This phrase, however, is often reserved for more formal occasions and should be used when around figures of authority.
Boss: I will be giving you a raise.
You: No way dawg, are you tickling my balls?
Boss: Nah I am so deadass
You: You are such a legend, homie
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.
