the use of slang is frequently ridiculed by culturally-ignorant people who feel it is the product of insufficient education and believe it to be counter-evolutionary; of course, they couldn't be farther from the truth. human language has been in a state of constant reinvention for centuries, and slang has been used and created by poets and writers of all sorts (William Shakespeare has been credited for the upbringing of at least a couple of words). it is the right and responsibility of the modern human to keep re-evaluating language, to give dead words innovative contemporary meanings or to simply invent new ones, in order to be more appealing and representative to the speaker/listener (which was essentially the basis behind language anyway, to understandably communicate thoughts or ideas verbally).
the use of and constant flux in slang is the only exciting thing happening in language, making present day especially interesting with the wealth of new words and definitions appearing seemingly everywhere. those who speak ill of slang obviously feel threatened or alienated by the evolution of a language they can't control, and all y'all trick ass marks need to stop running ya gums 'fore y'all gets slapped the fuck up...bitches.
peace and much love, the snizz.
