oy 

A term used between teens of DDP (Drunk Disorderly Punks) as a way of hollering at each other and saying "hi", since they are usually wandering the streets and need to yell to get attention. It also serves a double purpose of letting them know the one who yelled it is one of them.

"OY! WHATSUP???

oy 

Exclamation of surprise, amazement, etc.
Most probably stems from "oei!" A West-European word, similar to the English "Oh!" or "Oh dear!" or the more modern "What the hell?!".

Also used to attract attention.

Oy, what the hell do you think you're doing?

Oy 

The written version of putting the peace sign up to your face, the "O" signifying the head, and the "y" signifying the peace sign. The Oy can be thrown up to show allegiance to one's posse, or to complement an act of mutiny upon one's friends.

Although sometimes mistaken for an acronym or as a word in itself, it should actually be pronounced as two letters, not "Oi"
