Drunk Driving in my glasshouse...
He's talking about irrational behavior... how he's out of control sometimes, and how it all leads to the shit crashing down on him.
To summarize
irrational behavior - represented by drunk driving
his situation - represented by a glass house
What his uncontrolled, sometimes irrational behavior does to his situation - breaks down the glass house...
I'm enjoying that metaphor myself.
And yeah, Jevon stole it. He steals everything from Pac.
