The o-zone gettin' thinner, my pockets gettin' fatter
The world might end, I'm rich bitch, it don't matter
On Judgment Day I'm blinged out in a wife beater

from Bishop Lamont (Ft. The New Royals) – City Lights Lyrics on Rap Genius

Meaning

But if the world ends, Lamont is dressed up in a nice shirt and iced out with expensive jewelery, and that’s all what matters to him
