I have a good definiton for poser. My cousin. She is very cool, but is a pretty big poser. SHe recently started liking rock. Her favorite bands are Green Day, Panic! at the Disco, AFI, Simple Plan, My Chemical Romance...and thats pretty much it. I asked her if she knew "Death Cab for Cutie" "Blink 182" and even the old songs of Green Day...and she had NO IDEA. SHe painted her nails black, borrows her sisters black shirts(which says 'baby phat' on them, but as long as they are black, she doesnt care), and started to hate pink. Well, I like rock and metal, but I dont dress all in black. Her myspace is sooo emo and she tries to hit on emo kids. Her sisters call her goth, but she denies it. WHAT GIVES?! I mean, she doesnt even know what Oldies are!!!! She has no idea who Korn or Slipknot is. She shoudl just give up.

me: have you heard "all the small things."? its REALLY CATCHY!

Angela*: what is that? a new radio station.

a poser is a wannabe. basically a loser who tries to fit in by copying people they feel are COOL.
people who know a poser, should probably feel flattered. posers generally copy their friends, people who are unique get extremely P**sed at this :)

eg

Lauren: omg check out my myspace... its SOOO original
Elly: uhuh yea its so great you used your initiative, im so glad you copied and pasted my website into your blog :)

Jason was such a poser-biker; sure, he has a bike that's all black, but it doesn't even run and it is in pieces. He would rather spend his money going to Vegas.
