OMJ - Acronym for "Oh My Jonas!", used by fans of the Jonas Brothers. Taken from the internet term OMG. Note how "Jonas" has replaced "God" - the Jonas Brothers are a pop/rock icon that millions of girls everywhere worship.
"OMJ! That is so cool!"
"OMJ, did you go to the Jonas Brothers concert last night?"
"OMJ, Nick J is off the chain!"
