When you listen to the lyrics, you really begin to understand the full meaning, the "balls" is the pressure and weight that society is putting into yo jawz, blocking your mouth so you can't escape or speak up about it. But also notice the lyric "can i" before hand, meaning that you have a choice - that you are able to say no to having society push its balls in yo jawz. Truly a very inspirational, empowering song. In conclusion, we live in a society.
