to a fare-thee-well

To the most extreme degree, especially a condition of perfection. For example, We've cleaned the house to a fare-thee-well, or He played the part of martyr to a fare-thee-well. This term first appeared as to a fare-you-well in the late 1800s, and the more archaic-sounding present form replaced it about 1940.
