A reference to the phenomenon of continuously partying too hard while in the state of Texas, particularly Austin. Due to the large number of shows/fests and readily available booze and cocaine, Texcess has lead to many a hangover, regretted hook-up, hijinks and up-all-night partying. Texcessive partying is a problem often faced and readily dealt with by those who are known as "true ragers."
