Fairfield County, Connecticut. Fabled as rich and extravagent, but mostly mediocre. Some towns are home to areas that do fit the common description of 'the FC': Conyers farms in Greenwich, Smith and Oenoke Ridge in New Canaan, and bits of coastal Darien, Westport, and Fairfield (Southport).
"Man, I heard everyone in the FC has their own plane! Money grows on trees there!"
"Nah yo, ever seenNorwalk, Ridgefield, or Stamford? That's what I thought!"
A derogatory abbreviation meaning Fat Cunt. This is typically used among guys when talking about their overweight girlfriends without alarming them by calling them extremely foul terms. (see also bag.)
