New York City Expiration Date 

Hipsters and wannabe urbanites who move from suburban wastelands to NYC believing they will make it big in business, Broadway, or some other NY industry. Eventually, these mid-western suburbanites leave NYC generally after 1-2 years, after they realize they can't take the fast paced culture of NYC, get frustrated, and move to a more laid back city out west (Los Angeles, Seattle, or even back home). Those who expire are generally replaced with another hipster-suburbanite, who will eventually reach his/her expiration date, and the cycle continues.
