are sort of jive turkeys, they have a phobia of showing their true selves to the world, therefore; to counter-balance their fear, they try to fit-in by appealing to society and swallowing whatever the media shoves down their throats.
Alex is a preppy guy with almost no style that listens to whatever music his big brother listens to. One day, Alex becomes friends with Roger. Roger on the other hand has mad style, does graffiti and listens to underground RAP. A week later, Alex decides to start dressing up like Roger, listen to the same music and also claims to have a passion for graffiti...
Now my friends, this is a perfect example of a poser. Someone who's affraid to be judged, and rathers blending in... In sum, alex is a Robot, a society drone, an empty soul.
