Oh?

Encryption of a certain racial slur that begins with the character "N."

Vodka Enthusiast: "Oh?"

Jamal and his 28 black friends: "Ayo homie, what yo' white boy ass just say?"

Vodka Enthusiast: "I said 'Oh?', is there going to be an issue?"

Jamal and his 28 black friends: "No, but we just don't know what that means; we all dropped out of school at the age of 7."
Vodka Enthusiast: "I don't know, sounds like a YOU problem to me. It means 'Nig-'"

Jamal and his 28 black friends proceed to shoot the living shit out of Vodka Enthusiast.
