This is just a WAG (Wild Assed Guess), but it probably just symbolizes perceived oppression of any sort, be it from parents, school, society in general, etc. It just means ĎI wish I could do whatever I wanted without anybody trying to stop meí. Iíll Google it up and see if I canít come up with something a little more salient. Perhaps it has some significance with the Aryan prison/crystal meth subculture, I donít know. Maybe Taylor could shed some light on this, if itís true. An excellent place to ask this type of question is the Straight Dope Message Board
. Thereís an annual $15 membership fee, however.
