Rollin' down the street, smokin' indo
Sippin' on gin and Jews

He speaks English just fine. He spent six years in England for God's sake.

you are right guest :D I don´t remember this moment, but as a Portuguese, by reading his lips he looks like he´s saying "injustiça"

Does it mean something like unfair?

yup, it does :)
