An ifsy is a young woman who self-identifies as heterosexual, but might, under certain circumstances, engage in a meaningful sexual relationship with another woman.

An ifsy differs from a traditional bi-curious girl in that her potential interest extends beyond a casual physical encounter with another girl.

Since Miranda broke up with Jacob, she's been flirting with Sara a lot. I wonder if Jacob knew she was an ifsy.

Shackteâu

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.
