Y.O.  

The Y.O. (Yonkers) is one of the chillest places in New York. It's basically the Reno of the East Coast because it has a casino, prostitutes, and retarded cops. Every single person from Yonkers is an O.G. So the entire population is O.G., Proof: DMX, Jadakiss, Mary J Blige, and James Blake are all from Yonkers and the guy who invented FM radio, so without the Y.O. there would be no Hot 97. Conclusion: Yonkers is ballin

A- Waddup? I'm from the Y.O.
B- For serious? You must be O.G.
A- Word.

Short for Yonkers, it is an area included in Westchester, N.Y. where you have two sides - the ghetto and the white people. The line between these two has become blurry but if you go to the southside - Ghetty Square - you'll find where all the gangstas are at. And for sure, in the "good" side you'll find little white kids hanging around every sreet corner such as Central, Yonkers Ave., or any park and they'll either be having sex, getting drunk or high, or all these social activities combined. These white kids have their own "gangs" reppin' the street the chill at thinking they are hard ass niggas and certified gangstas.
