We put a line on our maps to define east and west, but in reality everyone can be the east side to your location or the west... But i guess we usually mean by east as the 'primitive' side or undeveloped... so you find impulsive a priori norms, rather than sophisticated decisions.
"I am warning you, don't mess with my east side or you will get it all wrong!!!!"
The softer part of town where average-to-wealthy families reside. Usually is occupated by wangsters who think they are black or even better than the blacks of the West.
East side whites get scraped down by da niggas from da west everyday.
