Rap song with sample link - must have high rap IQ; googling lyrics does not work

warning: this link has partial nudity in the video of a wet t-shirt contest, nonetheless, i would like the name of the first song in the background identified.

the rapper sounds southern to me. something about "everybody has a hustle what's yours?" for the hook. i'm thinking it could be late 90s to mid-to-late 2000s
