I may be wrong, but, here is what i think the song 'may' be about/mean:
Someone who is fake - ''plastic''.
Someone who sits in there house/room all day - ''He looks as if he hasnt slept, his hair is purposely unkept; The shadows underneath the eyes''.
But lies and says he's 'been out' - ''Is he really on the street; everywhere the bastard lies''.
But because he has no friends, cause he is always 'indoors', the person cant tell if he is liying - ''My lack of Proof is your disguise''.
''I could be wrong unless you play your game'' - He is liyin/ playing a game, so he deceivs him. ;s
''what he's wearing on his feet won't solve our mystery'' like, looking at what he is wering on his feet aint gonna help to prove he is a liying bastard ;s
... i aint quiet worked out that final bit ;s
.. but hopefully you get my drift. :S
