When you think you are 'straight' and meet someone of the same gender/sex that you seem to be attracted to in a romantic or sexual way. Can vary from person to person.
I've never really been attracted to girls, but this one seems like a Light Bulb Crush.
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.
