Intelligence gained outside of school. Just as useful as book smarts, and in many cases more so. It can be divided into 4 categories.

1.Getting Along With Others- Knowing which questions to ask and not asking too many,being polite and friendly, but also being assertive.

2.Common Sense- Knowing who you can trust, which areas in town are good and which are bad, etc.

3.Self-defense-Knowing how to fight and fend off an attacker, especially if you are small.

4.BS-detection-Knowing when people are trying to fuck you over, reading their intentions, and knowing that most corporate advertisements are complete bullshit.

one who is knowledgible at some art of illegal activity. understands the code and conduct held within a certain crime family/ies.

the term came from the common street hoodlum who knows how to succeed in areas that don't necessaryly need a formal education to get ahead in life.

for instance a group(crew) of criminals enterprise at trafficing and selling narcotics. they need some type of illegal practice for processing, smuggling, marketing and laundering money for their underground buisness. since the buisness is illegal, they set rules and regulations to keep the buisness from toppling. in doing so they from a "family" to keep outsiders from interfering and make their own checks and balances within their own "family" inorder to get rid of any potential rogue members; some of the codes that one would hold is that they:
* did not cooperate with authorities
* maintained self-control in the face of adversity
* carried out vendettas to avenge any slight suffering by his family(gang)
* did not forgive or forget
* maintained his demeanor within his ranking in a criminal hierarchy

it could be as petty like knowning how to card a door open, start a car without keys to a professional con-artist, a hit man, loan shark, ect...

a tv show that has the most stupid, idiotic, brain dead people that were ever born.
street smarts would probably ask the question "are you to stupid to live?" and "did your mother ever have any children that lived?" these are the people that could answer these questions and probably get them wrong.
