an acronym for the upper east side of Manhattan. The UES refers to 57th through 96th streets, east of 5th avenue. The avenues on the UES are: Madison, Park, Lexington, 3rd, 2nd, 1st, York, and East End.
The teenagers of the UES have a reputation for being very posh, stuck up, and wealthy. There are many infamous private schools on the UES, including Brearley, Chapin, Dalton, Spence, and Marymount. Brearley and Chapin have a huge rivalry. However, contrary to popular belief, the school called Constance-Billard, from the Gossip Girl series, was invented for the series, and does not exist in the real world.
