OJN 

"Only joking Nigga"

For those people who are in a public place where the word nigger could be deemed quite offensive and might possibly result in a cap in yo' ass. So instead of literally saying "only joking nigger" all you have to do is say OJN.....

It basically means you're kidding, having a laugh, you're just messing around. But it can also be a filler for an awkward silence

Gill: I saw you dad today.

Gill: Yeah, getting in the car with that slut Emily...
Charlie: .........
Gill: OJN :)
