The appropriately named "FU Center" is the new home of the Philadelphia 76ers, and, more importantly, the Philadelphia Flyers.

It's a beautiful modern building located in South Philadelphia next to the hideous structures of the First Union Spectrum and Veterans Stadium. Originally the CoreStates Center, this building changed names when First Union bought out CoreStates. Flyers fans are arguably the most rabid fans in all of hockey, and they enjoy telling opposing teams what the "FU" really stands for.
