Anthony & Cuta were playing XBOX for 12 hours straight when Anthony finally dominated the game and made Cuta wish he had won.
Anthony: OSN! I dominated that game.
Cuta: What is this a contest?
Anthony: In your face!
Cuta: Wish I drove a soup kitchen van.

Osn

For blacks, omg was officially ruled for whites. whenever a black person would use "omg" they would instead use "osn" which means "Oh Shit nigga!".

White person example:
Guy 1: Hey did you do biology homework?
Guy 2: Omg i totally forgot about that.

Black people
Guy 1: Ay did you do biology?
Guy 2: Osn, i forgot all about that.

OSN!

"Oh shit nigga!"

A Black version of "OMG", which IS too white of a term to use for Blacks.

An acronym not meant to be used by anyone who isn't Black.

OSN! I lost my "Chris Rock: Bigger & Blacker" DVD!
