A common picture on 4chan of a young man, giving the thumbs up sign and grinning eagerly in front of a yellow sports car, thus giving him the name 'happy hipster', for his fad of sports cars and his friendly grin.

It is mainly found on /b/, though every board has taken this fad.

Using a variety of IP scramblers, proxies, and ISP accounts, hipster troll spends a good deal of his ample free time giving 25 thumbs down ratings a day to any definition of "Hipster" that he finds critical, negative, and offensive on Urbandictionary.com.

For verification of hipster troll's activities, go to the first page for "hipster," write down the number of thumbs down given for any critical definition, and then come back the next day to see 20-30 more thumbs down. Similarly, go to the positive definition and watch it go 25 thumbs up in a day.

When a hipster undergoes the humiliation of not knowing a popular hipster reference.

A grief hipster is someone who, upon the death of a celebrity/well known public figure, will profess "Well, I don't give a shit they died. And you know what? This obscure other person died and nobody but me cared!" to show that not only are you being a sheep for being upset a public figure died but that they found someone more obscure to mourn than you.

People who think they are hipsters but really live in the suburbs and live in a townhouse and commute in their parents uneco friendly SUV. They think Andy Warhol is god and when asked can't name any works of art. They are not artistic and write lame poetry that is straight out of Dr.Suess with a hint of Dassboard. They buy half tights from Hollister and tell themselves have hip they are. The real hipsters don;t call themselves hipsters anThe d certainly do not read the hipster handbook. Hipster Scum also claim to be very liberal but are really jsut rebeling against there parents. It is rather sad to be a hipster scum of America because they think they are so special but really it has been done before.
