Also a song by Luniz a Bay Area rapper "I got 5 on it"

"no, me ain't my homie to begin with,
it's too many heads to be poppin at my friend hit it
unless you pull out the phat, crispy
5 dollar bill on the real before its history
cos fools be havin the vaccum lungs,
an if you let em hit it for free,
you hellar "dum-dum-dum-dum"

I got 5 on it,
grab your 40, let's get keyed
I got 5 on it,
messin wit that Indo weed
I got 5 on it,
it's got me stuck and not go back
I got 5 on it,
potna lets go half on a sack

- Luniz
