A young adult who's major accomplishment in life is considering themselves "cooler" than their surrounding society.
Hipster: you listen to the mainstream radio? Pffft, you're one of the sheeple.
Me: Wow, you're so much cooler than me. Congratulations. What an incredibly important accomplishment!
1. An arrogant ass-sucker who could find irony in a blowjob, but could not find a way out of his or her own sphincter
2. Someone who mistakenly considers himself or herself cooler (i.e. more "hip"), smarter, and more open-minded than others due to a misplaced sense of self-worth; also likes to refer to himself or herself as a "hipster"
Examples
1. Jason's hipster girlfriend gave him oral sex, then found it ironic that his jizz tasted like the food he had for dinner.
2. While sniffing her anus to confirm that her shit did not indeed stink, Jason's hipster girlfriend managed to stick part of her face into her butt. The paramedics had to come dislodge her head from her ass.
3. Some hipster was preaching about the differences between Plato and Aristotle on the street-corner. He had never read the works of Plato, nor of Aristotle, but he was convinced of his authority on the matter because he had good grades in classes other than philosophy and he wore hipster glasses with a hipster hairstyle.
A pretentious person who is decadent and weak through self-indulgences and makes attempts to 'stand out' or appear different from what they perceive to be the average person by wearing ostentatious clothing, and doing pretty much anything that calls attention to themselves. They are usually progressives.
He is such a hipster.
Hey! Look at that hipster over yonder! He (She) is listening to music, therefore, he (she) must truly enjoy it, because it is also creatively expressed through his (her) fashion and sweet, sweet dance (or lack of) dance moves.
A hipster is a gentrified hippy
Those hipsters look so skanky but smell like organic lavender oil
Not different enough to be interesting, but just different enough to be annoying.
My slightly too small font is so hipster.
A hipster is basically someone who thinks because you like mainstream things they are superior to you and they are 9/10 the ones who complains constantly about music in the current time but are the same ones that praise the music that they used to insult back in the days. They will typically insult anyone who likes mainstream music because they.....think they are not independent thinkers.
Non-hipster: Oh I like this song
Hipster: I don't
Non-hipster: Okay, what do you think is wrong
Hipster: It's brainwashing you and I don't want to be a corporate lap-dog, it's making you a follower so no one should like it.
Non-hipster: Get those negative and stereotypical superiority feelings away from me.
