Someone who acts just to keep up with a stereotype, and later instead of recognizing it, (Yes they're in denial) they tend to call others who aren't even close to a poser a 'Poser'. Pretty much, someone who believes they qualify for that certain label, but can't pull it off.
"Man, I'm Scene!" "Um, no, coon tail clip-ons and a BMTH shirt is not Scene, shut the fuck up, you Poser."
A poser is someone with no friends and is most likely a real estate agent with a beard and a BMW
Look at that poser! He even parked his beemer in the driveway of the house hes selling.
(TYPICALLY METAL GENRE) a poser is someone using a specific genre/band as a way to impress someone. for example, if your crush says they like the misfits, you buy a misfits shirt, not knowing any of their songs or anything about them.

little rant-
people keep saying that bands like SOAD, deftones and other "nu metal" bands are poser bands just because they don't sound like black sabbath, metallica, iron maiden, slayer, megadeth, etc. there are many different sub-genres in metal, and it shouldn't restrict to JUST thrash, death, or other "heavier" sub-genres. SOAD and deftones aren't even really nu metal, they just do what they like to do. they're not poser bands. like what you like, and listen to whatever you want to listen to.
someone: *sees someone in a nirvana shirt* "hey, what's your favorite nirvana song?"
poser:"uh.. I don't know any.. I just think its cute."
someone:"poser.."
1.\Pos"er\: a person who habitually pretends to be something he is not.
My buddy just got a Mohawk and he is a total Poser.
That annoying bastard who works for a magazine and gets all the women.
Mindy- Awhh god that guy is like sooo sexeey
Rob- No... Hes a poser
A person who gives people the idea to think that they skate, when they really don't. An example of what a poser wears is Thrasher and anything from Zumiez. Some posers ride penny boards, which doesn't make them any less of a poser, but let's just be honest - at least they go on wheels. If you're a beginner skater, you aren't a poser, because you actually skate. If you're called a poser for being a beginner, kick that person in the balls.
