Esc is a short term for the word escape. Escape means leave in some kind of hurry. In button terms esc would mean to either tab out or pull up a menu in a game.
The ESC is Eastern Santa Cruz. just past the Santa Cruz mountains in Central California. It cradles Reggae/ Ska, Punk Rock and skateboarding as well as beach side cities. Commonly smelling of the Ocean, remnants of sand are on most of the weathered streets. The ESC has a lot of umbrella shaped trees and is a good place to walk like it's the concrete jungle and chill like it's Maui. The reggae-rock band The Expendable is an ESC band. The ESC is also found in their song Sinsemillia.
Dude let's head down to the ESC for some surf and skate. I need some place to hang for a while.
