The opposite of bourgeois. 'Street' implies hustle. Every man a potential enemy, every woman a potential hoe. Money is king. The cold reality of day to day life and achieving. Someone who is 'street' is ready to defend themselves at all times and jump on any opportunity to level up. The paradox is that anyone who gets comfortable loses all street cred. There is not one hip hop star today who has street cred, because they have all gone soft.
