This is a song about "Once in a lifetime"

Give her that d i'm outta 8 mile

For good at least once in a while

Once i met a leader

That don’t mean i’ma stunt her

And california on that jerk shit

Once upon atime ago a minute

That gal want me ride har

And once you at a bar

When it comes to spitting that fire

For good at least once in a while

But never once in a gang

She said she's never had a man

You can’t resist this, once in a lifetime temptation

Kevin durant you're an ant like my mother kin

I'm a pro rapper, you battled once

Smoke until i ain't got no lungs
