What is a poser? (in your own words)

[curvededge]

comment me on what you think a poser is or means?
To me someone is a poser when they say they are something but are not...They do it just to be cool. I was discussing with my cousin about why he wants a flag with the weed symbol on it and to me he is a "poser" for wanting it.
I would like to know your guy's defintion.

I'm stealing this from Thai's LJ:
Describe to me using a few words who you think I am? I'm curious to see how you guy's see me or don't. haha.

I know I'm a try hard when it comes to girls I like.
I just realized what a fool I am and can be.
I hate you, female persons, for your gard darn girlness!!!
and by that I mean your hot body's/
haha
just kidding
I love you
