--> On the Intro - We gotta, we gotta, we gotta, we gotta get dat gangsta shit, come on!
We gotta get dat gangsta shit - come on! We gotta get dat gangsta shit come on, we gotta get dat, get dat gangsta shit
We gotta get dat gangsta shit, come on, we gotta get dat gansta shit, comeon, we gotta get dat shit, get dat shit, get dat shit (woo haa...) come on, come on....

--> Throughout the song - We gotta get dat gangsta shit - come-on!

--> In the foreground - What we doin' when the? What we doin' when the? What we doin' when the Fatboy's slippin'?
