The term "do it big" came from a city in Louisiana called Baton Rouge. It was first heard throughout state of Louisiana by an artist know as LIL BOOSIE, not the headbussas. The term means if you're going to do something do it to the fullest of your abilities.
Nigga, if you gone slab that hoe out, you might as well do it big by putting the swaggaz on that hoe.
