OMFJ is the acronym of 'Oh my Freckled Jesus'

Freckled Jesus is also known as Marco Bott, from Attack on Titan.
Vanessa: "OMFJ I JUST FINISHED ATTACK ON TITAN"

Bob: "REALLY? THAT'S SO COOL!"

"Oh my fucking Jonas" (Jonas Brothers reference)

Like OMJ but with much more emotion behind it

"OMFJ, why didn't you get their autograph for me!"
