2. poser
Someone who spends all or most of their time trying to find out whats "cool" or "in". Once they know what is "in" they do it no matter what their personal veiws on it are. Posers usually pose off of what is on MTV or VH1 or their local "hot" radio station, because they think they will be accepted for it. Normally posers also take whatever they are posing off of to an abnormal and unhealthy extreme. Posers change their style to fit what's "cool". They are usually the losers who have a myspace and comment the people who origionally wore the style they pose off of saying "I LOVE YOU SOOO MUCH!!<33" even though they either don't know them, or the origional hates them. Posers often have "myspace pics" or "emo pics" on their myspace. They are often always hated by everyone else they know except their poser friends. Posers also sometimes write and/or talk in "internet lingo" while not on the internet. Most also over use the famous comeback of "your mom".
