A few "entertaining" definitions of hipster:
1-The defining attribute of a hipster lies in their disdain for others of their own kind.
2-The personification of insecurity, brattiness and bizarre sense of entitlement.
The prevalence of hipsters in a neighborhood is an indicator for gentrification.
3-the hipster mecca is in williamsburg brooklyn. it's a subculture of kids born in the 80's. it started with mutton chops & buddy holly glasses, but has now progressed progressed into trucker caps, pointy shoes, and the god awful rehash of the mullet.
typically, hipsters are "slumming it" on mommy & daddy's dime. a full blown hipster reduces himself by never wearing anti-perspirant & appearing to be poor. drink of choice is rheingold, or pabst blue ribbon beer.
4-The modern Bohemians. A mid-twenties person who works at a low paying job, is interested in "Artsy things" Hipsters tend to swarm around the determined "Hipster" part of town, ex. Wicker Park in Chicago. Hipster Ladies should have short hair and wear thrift shop clothes and Male Hipsters should be anemically skinny to let people know that they are poor and cant afford enough food.
5-someone, usually a teenager or 20something, who adheres to a counterculture ranging from indy-rockers to neo-hippies to skaters. they tend to define themselves by the music they listen to, and the outlandish clothes they wear. hipsters are opposed to other countercultures like goths, metal-heads, and gangstas, and they also avoid preps, eurotrash, white trash, and jocks

6-people in thier teens to 20s who generally listen to indie rock, hang out in coffee shops, shop at the thrift store and talk about things like books, music, films and art.
7-teenager to twenty something who like to hang out in local coffeehouses and art gallerys, and think they're better then everyone else because they're not mainstream. They like vintage clothing and anything that looks like it's been sitting in a closet for upward of twenty years.
8-Seattle-dwelling, emo-listening, black hair-dye using, counter-culture adhering socially infantalistic subgroup of individuals from the upper middle class who fiegn angst and a difficult life with a jaded facade of indifference. Fail to realize they are the most narrow minded people to walk this earth, next to the FCC.
9-n. someone who flaunts cigarettes.
10-lovely people who try to be different by listening to unique music and wearing obscure clothing usually found at a thrift store. they somehow pull of a in style look by wearing really old clothes they got for next to nothing. very artsy. obcessed with the past, and anything 'vintage'
